Kaspersky 3.x to 4.x allows remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on a target system. Anti-virus software may rely on corrupted headers to determine if a zip archive is valid. As a result, anti-virus software may fail to detect malicious content within a zip archive. Multiple Vendor Antivirus applications are reported vulnerable to a zip file detection evasion vulnerability. This vulnerability may allow maliciously crafted zip files to avoid being scanned and detected. The malicious archive can bypass the protection provided by a vulnerable antivirus program, giving users a false sense of security. If the user opens and executes the file, this attack can result in a malicious code infection. This issue is reported to affected products offered by McAfee, Computer Associates, Kaspersky, Sophos, Eset and RAV. Latest antivirus products by Symantec, Bitdefender, Trend Micro and Panda are not vulnerable to this issue. Kaspersky is a well-known antivirus software. Kaspersky 3.x and 4.x versions have issues when processing .zip files, resulting in a vulnerability to bypass antivirus checks. II. DESCRIPTION Remote exploitation of an exceptional condition error in multiple vendors' anti-virus software allows attackers to bypass security protections by evading virus detection. The .zip file format stores information about compressed files in two locations - a local header and a global header. The local header exists just before the compressed data of each file, and the global header exists at the end of the .zip archive. It is possible to modify the uncompressed size of archived files in both the local and global header without affecting functionality. This has been confirmed with both WinZip and Microsoft Compressed Folders. An attacker can compress a malicious payload and evade detection by some anti-virus software by modifying the uncompressed size within the local and global headers to zero. III. ANALYSIS Successful exploitation allows remote attackers to pass malicious payloads within a compressed archive to a target without being detected. Most anti-virus engines have the ability to scan content packaged with compressed archives. As such, users with up-to-date anti-virus software are more likely to open attachments and files if they are under the false impression that the archive was already scanned and found to not contain a virus. IV. The Vendor Responses section of this advisory contains details on the status of specific vendor fixes for this issue. V. WORKAROUND Filter all compressed file archives (.zip) at border gateways, regardless of content. VI. VENDOR RESPONSES McAfee "The McAfee scan engine has always been a market leader in detection of viruses, worms and Trojans within compressed and archived file formats. As such the mechanism used for the detection of such payloads has been designed to ensure all archive files are thoroughly scanned at each nested level in the file to ensure that all appropriate parts of the file are scanned. McAfee is aware of a proof of concept exploitation in Zip archive payloads where information in the local header part of the archive is modified. The local header exists just before the compressed data of each file. It is possible to modify the uncompressed size of archived files in the local header without affecting functionality. Consequently there is the potential for a malicious payload to be hidden and avoid anti-virus detection by modifying the uncompressed size within the local headers to zero. The techniques used by McAfee to analyze Zip archives have allowed a comprehensive solution for the Zip file format vulnerability to be provided to protect customers. The latest update for the current 4320 McAfee Anti-Virus Engine DATS drivers (Version 4398 released on Oct 13th 2004) further enhances the protection afforded to McAfee customers against such potential exploits. A DATS Driver update issued in Version 4397 (October 6th 2004) provided early protection for the same potential exploit targeted specifically for Gateway and Command line scanning. If a detection of this type of exploit is found it will trigger the message "Found the Exploit-Zip Trojan!" to be displayed. Updates for the DAT files mentioned above can be located at the following links: Home (Retail) Users: http://download.mcafee.com/uk/updates/updates.asp Business (Enterprise) Users: http://www.mcafeesecurity.com/uk/downloads/updates/dat.asp?id=1 It should be noted that whilst McAfee take the potential for this exploit to be used maliciously seriously, to date no evidence of such an exploit has been discovered. McAfee has provided additional protection through the DATS driver update however with usage of the comprehensive suite of anti-virus protection strategies provided by McAfee products, MacAfee are confident that this exploit presented no additional threat to its customers. It should be noted that with McAfee on-access scanning active, such modification for malicious purposes to hide payloads only delays eventual detection - McAfee on-access detection will detect any payload with malicious intent as malware. McAfee continues to focus on ensuring that customers receive maximum protection and provide a rapid response to all potential vulnerabilities thus ensuring customer satisfaction." Computer Associates "With the assistance of iDEFENSE, Computer Associates has identified a medium-risk vulnerability in a shared component of eTrust Antivirus which may allow a specially crafted .ZIP file to bypass virus detection. A number of CA products embed this technology including solutions from eTrust, Brightstor and others. Customers are encouraged to visit the CA support web site below for more information about this vulnerability, a list of products and platforms that are effected, and remediation procedures. http://supportconnectw.ca.com/public/ca_common_docs/arclib_vuln.asp. At Computer Associates, every reported exposure is handled with the utmost urgency. We strive to ensure that no customer is left in a vulnerable situation." Kaspersky (09/24/2004) "...this bug for scanners based on 3.x-4.x engines will be fixed in next (not current) cumulative update. For scanners based on new 5.0 engine we recommend you waiting for the release of our next maintenance pack. We are going to release it in October." Sophos "A vulnerability has been discovered in Sophos's handling of Zip archive files, whereby a Zip file can be deliberately altered to prevent accurate scanning by Sophos anti-virus products of its contents. Although theoretically a risk, Sophos has not seen any examples of malware attempting to employ this vulnerability. Furthermore, The vulnerability does not prevent Sophos's desktop on-access scanner from correctly detecting viruses (and preventing actual infection) which manage to bypass the email gateway software, so the risks of infection are very small. Sophos has enhanced its scan engine to deal with malformed Zip files. Version 3.87.0 of Sophos Anti-Virus on all operating system platforms except Windows 95/98/Me includes this fix and customers will be automatically updated to this version via EM Library from Wednesday 20 October 2004. Additionally, a version of the software will be available for download from the Sophos website from Friday 22 October 2004. Sophos Anti-Virus for Windows 95/98/Me customers will be updated with the fix from version 3.88.0 (available from 24 November 2004). Sophos thanks iDEFENSE for their assistance in identifying this vulnerability." Eset "The vulnerability was caused by the fact that some archive compression/decompression software (including Winzip) incorrectly handles compressed files with deliberately damaged header fields, thus, in-fact, allowing creation of the damaged archive files, that could be automatically repaired on the victims computer without notifying the user. Eset has made appropriate modifications to archive-scanning code to handle such kind of archives immediately after receiving notification from iDEFENSE. These changes are contained in archive-support module version 1.020, released on 16th September 2004 at 21:00 CET. The update was available for all clients with Automatic Virus-Signatures Update set." RAV No vendor response VII.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files. libtiff of tif_next.c , tif_thunder.c , tif_luv.c In RLE In the process of decompressing a compressed file, a buffer overflow vulnerability exists due to improper bounds checking.Crafted by a third party TIFF Format image files LibTIFF Interpretation via applications and components that use the library will cause the application to crash and cause denial of service (DoS) It may be possible to run into arbitrary code with the privileges of the target user. LibTIFF is affected by multiple buffer-overflow vulnerabilities because the software fails to properly perform boundary checks before copying user-supplied strings into finite process buffers. An attacker may leverage these issues to execute arbitrary code on a vulnerable computer with the privileges of the user running a vulnerable application, facilitating unauthorized access. The attacker may also leverage these issues to crash the affected application. libtiff is an application library responsible for encoding/decoding TIFF image format. kfax is a small tool for displaying FAX files, using the libtiff library. There is a problem with libtiff when processing fax files. kfax calls the libtiff library to process .g3 files. Attackers can build malformed .g3 files and entice users to process them, which can lead to buffer overflows. Carefully constructed file data may execute arbitrary instructions with user process privileges. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 567-1 security@debian.org http://www.debian.org/security/ Martin Schulze October 15th, 2004 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : tiff Vulnerability : heap overflows Problem-Type : remote Debian-specific: no CVE ID : CAN-2004-0803 CAN-2004-0804 CAN-2004-0886 Several problems have been discovered in libtiff, the Tag Image File Format library for processing TIFF graphics files.

The WebDAV Message Handler for Internet Information Services (IIS) 5.0, 5.1, and 6.0 allows remote attackers to cause a denial of service (memory and CPU exhaustion, application crash) via a PROPFIND request with an XML message containing XML elements with a large number of attributes. Microsoft XML Parser is prone to a remote denial of service vulnerability when handling malformed requests. The vulnerability can be exploited through the WebDAV XML message handler of Microsoft IIS server. It is reported that this issue requires a remote attacker to create specially crafted WebDAV requests and send them to a vulnerable server over TCP port 80. There is a possibility of increased CPU resource and memory consumption as the IIS server attempts to process these requests. This can eventually lead to a denial of service condition in the server. A reboot is required to restore normal functionality. This vulnerability can also be exposed through other applications that rely on Microsoft XML Parser to process XML messages

MySQL MaxDB before 7.5.00.18 allows remote attackers to cause a denial of service (crash) via an HTTP request to webdbm with high ASCII values in the Server field, which triggers an assert error in the IsAscii7 function. A remotely exploitable denial of service vulnerability exists in MaxDB. This will reportedly trigger an exception due to an assert directive failing, resulting in a denial of service condition in the web agent. This issue was reportedly tested on Windows and Linux versions. Other versions could also be affected. MySQL MaxDB Web Agent WebDBM Server Name Denial of Service Vulnerability iDEFENSE Security Advisory 10.06.04a: www.idefense.com/application/poi/display?id=150&type=vulnerabilities October 6, 2004 I. BACKGROUND MaxDB by MySQL is a re-branded and enhanced version of SAP DB, SAP AG's open source database. MaxDB is a heavy-duty, SAP-certified open source database that offers high availability, scalability and a comprehensive feature set. MaxDB complements the MySQL database server, targeted for large mySAP ERP environments and other applications that require maximum enterprise-level database functionality. II. The problem specifically exists due to improper input validation of a user-supplied variable in the IsAscii7() function. wahttp: ToolsCommon/Tools_DynamicUTF8String.hpp:249: Tools_DynamicUTF8String::Tools_DynamicUTF8String(const SAPDB_Char *) Assertion `IsAscii7(src)' failed. Program received signal SIGABRT, Aborted. [Switching to Thread 10251 (LWP 12706)] 0x40429781 in kill () from /lib/libc.so.6 III. IV. DETECTION iDEFENSE has confirmed that SAP DB version 7.5 for both Linux and Windows is vulnerable. V. WORKAROUND Use of an ingress perimeter firewall filter can help detect and mitigate the risk of attack. VI. VENDOR RESPONSE "A solution for the issue is available with MaxDB 7.5.00.18." VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the names CAN-2004-0931 to these issues.

RealNetworks Helix Universal Server 9.0.2 for Linux and 9.0.3 for Windows allows remote attackers to cause a denial of service (CPU and memory exhaustion) via a POST request with a Content-Length header set to -1. The problem surrounds the mishandling of some POST headers values. An attacker can exploit this issue to cause the affected server to consume excessive computer resources and hang, denying service to legitimate users. BACKGROUND RealNetworks Helix Universal Server is a universal digital media delivery platform with industry leading performance, integrated content distribution and Web services support. More information is available at http://www.realnetworks.com. II. The problem specifically exists in the handling of specially crafted POST requests. Generating a request with the Content-Length header set to -1 triggers an integer handling error resulting in mass utilization of memory and CPU time. III. ANALYSIS Any unauthenticated remote attacker can exploit this vulnerability, which causes the affected system to utilize mass amounts of memory and CPU time. The system will no longer be able to process future requests. The affected server must be restarted in order to resume normal functionality. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in RealNetworks Helix Server version 9.0.2 for Linux and version 9.0.3 for Windows. It is suspected that earlier versions on both platforms are vulnerable as well. V. WORKAROUND Usage of an inline application level filter can help mitigate risk of exploitation by scanning for and filtering invalid Content-Length parameters. VI. VENDOR RESPONSE "Customers are encouraged to upgrade their Server software to the latest version, which contains a security patch." RealNetworks has released binaries that guard against the described vulnerability. The related advisory from RealNetworks is available at: http://service.real.com/help/faq/security/security100704.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2004-0774 to this issue.

Buffer overflow in digestmd5.c CVS release 1.170 (also referred to as digestmda5.c), as used in the DIGEST-MD5 SASL plugin for Cyrus-SASL but not in any official releases, allows remote attackers to execute arbitrary code. Cyrus SASL is affected by multiple critical vulnerabilities that may be remotely exploitable. The first issue is due to a boundary condition error, the second issue is due to a failure of the application to properly handle environment variables. Information currently available regarding these issues is insufficient to provide a more detailed analysis. This BID will be updated and split into separate BIDs when more information becomes available. An attacker can leverage the boundary condition issue to exploit arbitrary code on the affected computer. The impact of the environment variable issue is currently unknown. Cyrus SASL provides several open source implementations for security authentication. Cyrus SASL incorrectly handles the SASL_PATH environment variable, which could be exploited by a local attacker for privilege escalation attacks. Attackers can use the SASL_PATH environment variable to make privileged applications load arbitrary library files from any directory specified by the user, which can cause malicious programs to run with high privileges

Symantec Norton AntiVirus 2004, and earlier versions, allows a virus or other malicious code to avoid detection or cause a denial of service (application crash) using a filename containing an MS-DOS device name. Norton AntiVirus is affected by a scan evasion vulnerability when handling files with MS-DOS reserve device names. This issue is due to a design error that allows the files to avoid being scanned. It should be noted that this vulnerability only arises once the file is already present on a vulnerable computer. All Norton AntiVirus products are able to detect malicious files through incoming email. BACKGROUND Symantec's Norton AntiVirus protects email, instant messages, and other files by automatically removing viruses, worms, and Trojan horses. More information about the product is available from http://www.symantec.com II. The problem specifically exists in attempts to scan files and directories named as reserved MS-DOS devices. Reserved MS-DOS device names are a hold over from the original days of Microsoft DOS. The reserved MS-DOS device names represent devices such as the first printer port (LPT1) and the first serial communication port (COM1). Sample reserved MS-DOS device names include AUX, CON, PRN, COM1 and LPT1. reserved device names can be creating with standard Windows utilities by specifying the full Universal Naming Convention (UNC) path. The following command will successfully copy a file to the reserved device name 'aux' on the C:\ drive: copy source \\.\C:\aux III. ANALYSIS Exploitation allows attackers to evade detection of malicious code. Attackers can unpack or decode an otherwise detected malicious payload in a stealth manner. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in the latest version of Norton AntiVirus. It is reported that earlier versions crash upon parsing files or directories using reserved MS-DOS device names. V. WORKAROUND Ensure that no local files or directories using reserved MS-DOS device names exist. On most modern Windows systems there should be no reserved MS-DOS device names present. While the Windows search utility can be used to locate offending files and directories, either a seperate tool or the specification of Universal Naming Convention (UNC) must be used to remote them. The following command will successfully remove a file stored on the C:\ drive named 'aux': del \\.\C:\aux VI. VENDOR RESPONSE "Symantec engineers have developed a fix for this issue for Symantec Norton AntiVirus 2004 that is currently available through LiveUpdate. The fix is being incorporated into all other supported Symantec Norton AntiVirus versions and will be available through LiveUpdate when fully tested and released." More information is available in Symantec Security Advisory SYM04-015. VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the names CAN-2004-0920 to these issues.

Postfix on Mac OS X 10.3.x through 10.3.5, with SMTPD AUTH enabled, does not properly clear the username between authentication attempts, which allows users with the longest username to prevent other valid users from being able to authenticate. This may potentially be exploited to deny certain users access to the server. This condition may only occur if SMTPD AUTH has been enabled. This issue reportedly does not affect the upstream release of Postfix but rather only the version distributed with Apple Mac OS X Panther. Apple Mac OS X is a dedicated operating system developed by Apple for Mac computers

NetInfo Manager on Mac OS X 10.3.x through 10.3.5, after an initial root login, reports the root account as being disabled, even when it has not. Multiple security vulnerabilities are reported in Mac OS X. A security update is available to address these issues and to provide other enhancements. The following issues are reported: Apple AFP server is reported prone to a remote denial of service vulnerability. A weak permissions vulnerability is reported to affect the AFP server. This may result in a false sense of security for an administrator. A vulnerability is reported to exist in the NetInfoManager utility. It is reported that the utility will, under certain circumstances, report the status of certain accounts as disabled when they are not. A heap-based buffer overrun is reported to exist in the QuickTime utility. An attacker may exploit this vulnerability to execute arbitrary instructions in the context of the user that is running the vulnerable software. Finally, ServerAdmin is reported prone to a weak default configuration vulnerability. This may result in ServerAdmin traffic being intercepted and decrypted by a remote attacker. This vulnerability has been split into BID 11344. Some of these issues may already be described in previous BIDs. This BID will be split up into unique BIDs when further analysis of this update is complete

AFP Server on Mac OS X 10.3.x to 10.3.5, under certain conditions, does not properly set the guest group ID, which causes AFP to change a write-only AFP Drop Box to be read-write when the Drop Box is on a share that is mounted by a guest, which allows attackers to read the Drop Box. Multiple security vulnerabilities are reported in Mac OS X. A security update is available to address these issues and to provide other enhancements. The following issues are reported: Apple AFP server is reported prone to a remote denial of service vulnerability. A weak permissions vulnerability is reported to affect the AFP server.

CUPS 1.1.20 and earlier records authentication information for a device URI in the error_log file, which allows local users to obtain user names and passwords. When an SMB printer is configured, CUPS stores plain text login information to the log file. CUPS (Common UNIX Printing System) Is SMB When outputting to a shared printer, device URI Included in ID Vulnerabilities exist where passwords are logged in the error log.SMB Host user providing a shared printer ID And you may get a password. CUPS is reported prone to a local password disclosure vulnerability. This issue is reported to present itself when an authenticated user carries out certain methods of remote printing. Reportedly, local attackers can disclose user passwords in the printing system log files. CUPS 1.1.21 and prior are considered vulnerable to this issue. Due to a lack of detail, further information is not available at the moment. This BID will be updated as more information becomes available. SOLUTION: The vulnerability has been fixed in the CVS repository.

ServerAdmin in Mac OS X 10.2.8 through 10.3.5 uses the same example self-signed certificate on each system, which allows remote attackers to decrypt sessions. Multiple security vulnerabilities are reported in Mac OS X. A security update is available to address these issues and to provide other enhancements. The following issues are reported: Apple AFP server is reported prone to a remote denial of service vulnerability. A weak permissions vulnerability is reported to affect the AFP server. This may result in a false sense of security for an administrator. A vulnerability is reported to exist in the NetInfoManager utility. It is reported that the utility will, under certain circumstances, report the status of certain accounts as disabled when they are not. A heap-based buffer overrun is reported to exist in the QuickTime utility. An attacker may exploit this vulnerability to execute arbitrary instructions in the context of the user that is running the vulnerable software. Finally, ServerAdmin is reported prone to a weak default configuration vulnerability. This may result in ServerAdmin traffic being intercepted and decrypted by a remote attacker. This vulnerability has been split into BID 11344. Some of these issues may already be described in previous BIDs. This BID will be split up into unique BIDs when further analysis of this update is complete. This vulnerability allows attackers to decrypt all communications between ServerAdmin servers and clients. This facilitates the theft of authentication credentials by sniffing networks containing the affected application, and then utilizing the known private key in applications such as 'ssldump'. Once authentication credentials are stolen, attackers can then utilize ServerAdmin for full system compromise. Previous versions may also be affected

AFP Server on Mac OS X 10.3.x to 10.3.5, when a guest has mounted an AFP volume, allows the guest to "terminate authenticated user mounts" via modified SessionDestroy packets. Multiple security vulnerabilities are reported in Mac OS X. A security update is available to address these issues and to provide other enhancements. The following issues are reported: Apple AFP server is reported prone to a remote denial of service vulnerability. A weak permissions vulnerability is reported to affect the AFP server. This may result in a false sense of security for an administrator. A vulnerability is reported to exist in the NetInfoManager utility. It is reported that the utility will, under certain circumstances, report the status of certain accounts as disabled when they are not. A heap-based buffer overrun is reported to exist in the QuickTime utility. An attacker may exploit this vulnerability to execute arbitrary instructions in the context of the user that is running the vulnerable software. Finally, ServerAdmin is reported prone to a weak default configuration vulnerability. This may result in ServerAdmin traffic being intercepted and decrypted by a remote attacker.

The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. A buffer overflow in certain Apple AirPort drivers may allow an attacker to execute arbitrary code with system privileges, or create a denial-of-service condition. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. OpenSSL include der_chop The script contains a flaw that creates a temporary file in an inappropriate way for security reasons, so there is a vulnerability that is subject to symbolic link attacks.der_chop An arbitrary file may be created or overwritten with the privileges of the user executing the script. OpenSSL is affected by an insecure temporary file creation vulnerability. This issue is likely due to a design error that causes the application to fail to verify the existence of a file before writing to it. An attacker may leverage this issue to overwrite arbitrary files with the privileges of an unsuspecting user that activates the vulnerable application. Reportedly this issue is unlikely to facilitate privilege escalation. OpenSSL is an open source SSL suite. ---------------------------------------------------------------------- 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.

Moore has reported a vulnerability in the Apple Airport driver, which potentially can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to an error in the Airport driver provided with Orinoco-based Airport cards when handling probe response frames. This can be exploited to overwrite kernel memory and potentially execute arbitrary code when the driver is running in active scanning mode. The vulnerability is reported in the driver on a PowerBook running version 10.4.8. Other versions may also be affected. SOLUTION: Do not place the card into active scanning mode.

It should also be noted that the discoverer of the issue has not provided any details about which versions may be affected by this issue, version information will be updated appropriately when this issue is investigated further

Inkra Router Virtual Service Switch is a device implemented by a routed virtual service exchange, which dynamically protects against internal networks and applications. Inkra Router Virtual Service Switch incorrectly handles abnormal network data. Remote attackers can use this vulnerability to conduct denial of service attacks on devices. No detailed vulnerability details are provided at this time. This issue is due to a failure of the application to handle exceptional network data. An attacker may leverage this issue to cause the affected device to crash, denying service to legitimate users

Motorola Wireless Router WR850G running firmware 4.03 allows remote attackers to bypass authentication, log on as an administrator, and obtain sensitive information by repeatedly making an HTTP request for ver.asp until an administrator logs on. Motorola WR850G is a wireless router.  The attacker gains access to the WEB interface through periodic access restricted 'ver.asp' scripts, and can obtain the WEB interface user name and password. Using this password, by accessing frame_debug.asp, the WEB SHELL can be obtained and executed on the system. Any command. This issue is caused by a design error and may allow an attacker to ultimately take complete control over the device. Motorola wireless router WR850G running firmware version 4.03 is reportedly affected by this issue. It is possible that other models and firmware versions are affected as well
