iDEFENSE Security Advisory 11.15.05 - The Microsoft Windows API includes the CreateProcess() function as a means to create a new process and it's primary thread. CreateProcessAsUser() is similar but allows for the process to be run in the security context of a particular user.
Multiple Vendor Insecure Call to CreateProcess() Vulnerability iDEFENSE Security Advisory 11.15.05 www.idefense.com/application/poi/display?id=340&type=vulnerabilities November 15, 2005 I. BACKGROUND The Microsoft Windows API includes the CreateProcess() function as a means to create a new process and it's primary thread. CreateProcessAsUser() is similar but allows for the process to be run in the security context of a particular user. II. DESCRIPTION The format of the CreateProcess() function is as follows: BOOL CreateProcess( LPCTSTR lpApplicationName, LPTSTR lpCommandLine, LPSECURITY_ATTRIBUTES lpProcessAttributes, LPSECURITY_ATTRIBUTES lpThreadAttributes, BOOL bInheritHandles, DWORD dwCreationFlags, LPVOID lpEnvironment, LPCTSTR lpCurrentDirectory, LPSTARTUPINFO lpStartupInfo, LPPROCESS_INFORMATION lpProcessInformation ); The 'lpApplicationName' variable contains the name of the module to be executed. However, this can be a NULL value, in which case, the module name to be executed will be the first white space-delimited token in the lpCommandLine string. It is a known issue, that if lpApplicationName contains a NULL value and the full module path in the lpCommandLine variable contains white space and is not enclosed in quotation marks, it is possible that an alternate application will be executed. Consider the following scenario: CreateProcess( NULL, c:\program files\sub dir\program.exe, ... ); In this case, the system will successively expand the string when interpreting the file path, until a module is encountered to execute. The string used in the above example would be interpreted as follows: c:\program.exe files\sub dir\program name c:\program files\sub.exe dir\program name c:\program files\sub dir\program.exe Therefore, if a file named program.exe existed in the c:\ directory, it would be executed instead of the intended application. This is a known issue, discussed directly in the API documentation: http://msdn.microsoft.com/library/en-us/dllproc/base/createprocessasuser.asp III. ANALYSIS Despite the fact that this is a known issue, several popular applications, insecurely call the CreateProcess() and CreateProcessAsUser() functions. This creates a scenario whereby arbitrary code could be executed. In the scenario detailed above, if an attacker were able to install arbitrary code in a file at c:\program.exe, when the vulnerable application was launched, the code would be executed. The arbitrary code would generally be executed under the privileges of the executing user but could also be launched with elevated privilegs if an insecure call were made CreateProcessAsUser() using elevated privileges. This attack would involve some form of social engineering or need to be combined with another attack to first get the arbitrary code installed in the correct location. IV. DETECTION The following applications have been confirmed to be vulnerable: Vendor: RealNetworks Application: RealPlayer 10.5 Files: realplay.exe realjbox.exe Vendor: Kaspersky Application: Kaspersky Anti-Virus for Windows File Servers 5.0 (English) - Installation File Files: kav5.0trial_winfsen.exe Vendor: Apple Application: iTunes 188.8.131.52 Files: iTunesHelper.exe Vendor: VMWare Application: VMWare Workstation 5.0.0 build-13124 Files: VMwareTray.exe VMwareUser.exe Vendor: Microsoft Application: Microsoft Antispyware 1.0.509 (Beta 1) Files: GIANTAntiSpywareMain.exe gcASNotice.exe gcasServ.exe gcasSWUpdater.exe GIANTAntiSpywareUpdater.exe Note: The vulnerability in Microsoft Antispyware was previously discussed on the Full-Disclosure mailing list (http://lists.grok.org.uk/pipermail/full-disclosure/2005-May/033909.html) but remains unpatched. V. WORKAROUND Ensure that unexpected files are not stored in locations that can be used for this attack. Windows XP SP2 will alert a user of the existence of a file named c:\program.exe when it first boots, however, any path containing white space where a vulnerable application is stored could be used in this attack. VI. VENDOR RESPONSE The following vendor responses have been provided. Apple: "Due to the way iTunes 5 launches its helper application, multiple system paths are searched for which program to run. This may allow a malicious user on the local system to create an environment where an alternate program will be executed by iTunes. iTunes 6 addresses this issue and can be obtained from http://www.apple.com/itunes/download/. Credit to iDEFENSE for reporting this issue to us." Kaspersky: "We are currently looking into the problem, and it seems that this is not present in the current version of KAV for File Servers." Microsoft: "Microsoft has confirmed that the Beta 2 version of its Antispyware product, targeted for release later this year, will address the issue reported by iDEFENSE." VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the following names to this issue. RealNetworks RealPlayer 10.5 CAN-2005-2936 Kaspersky Anti-Virus 5.0 CAN-2005-2937 Apple iTunes 184.108.40.206 CAN-2005-2938 VMWare Workstation 5.0.0 build-13124 CAN-2005-2939 Microsoft Antispyware 1.0.509 (Beta 1) CAN-2005-2940 Theses are candidates for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems.

iDEFENSE Security Advisory 10.10.05-2 - Remote exploitation of a buffer overflow vulnerability in Kaspersky Labs' Anti-Virus Engine allows remote attackers to execute arbitrary code. Kaspersky Anti-Virus Engine is used by multiple vendors in Linux virus scanner products and exploitation requires minimal interaction by a targeted user.
Kaspersky Anti-Virus Engine CHM File Parser Buffer Overflow Vulnerability iDEFENSE Security Advisory 10.10.05 www.idefense.com/application/poi/display?id=318&type=vulnerabilities October 10, 2005 I. BACKGROUND Kaspersky Anti-Virus Engine (KAV) is a popular virus scanning engine for Windows and Linux. The Kaspersky Anti-Virus Engine is commonly included in various vendors' network mail gateway and host-based anti- virus products. II. DESCRIPTION Remote exploitation of a buffer overflow vulnerability in Kaspersky Labs' Anti-Virus Engine allows remote attackers to execute arbitrary code. Kaspersky Anti-Virus Engine is used by multiple vendors in Linux virus scanner products and exploitation requires minimal interaction by a targeted user. The Kasperksy Anti-Virus Engine (KAV) is found in many gateway and host-based anti-virus scanners. The vulnerability specifically exists in the CHM file parser within the KAV engine. When a corrupt CHM file is scanned by the KAV engine, a heap overflow can occur which allows remote attackers to execute arbitrary code with permissions of the anti-virus application's process, usually user privileges. On Microsoft platforms, affected software has not been shown to execute arbitrary code, however Kaspersky Anti-Virus will fail to scan any files after a corrupt CHM file has been encountered, thus allowing further malicious codes to reach the target. III. ANALYSIS Successful exploitation of the vulnerability can result in remote arbitrary code execution or the disabling of anti-virus functionality. In the case of Linux platforms, specifically network gateways, user interaction is not required and can lead to the compromise of trusted systems. In addition, compromising mail gateways can lead to further compromise of internal hosts by injecting malicious code into mail attachments. IV. DETECTION iDEFENSE Labs has confirmed the existence of this vulnerability in the following products (tested April 2005): * Kaspersky Personal 5.0.227 * Kaspersky Anti-Virus On-Demand Scanner for Linux 5.0.5 * F-Secure Anti-Virus for Linux 4.50 All products utilizing the Kaspersky Anti-Virus engine are potentially vulnerable. The vendor has notified iDEFENSE that the vulnerability has been addressed via a signature update. Users who have updated their signatures after July 2005 are reportedly not affected. V. WORKAROUND iDEFENSE is currently unaware of any effective workarounds for this issue. VI. VENDOR RESPONSE The vendor has notified iDEFENSE that the vulnerability has been addressed via a signature update. Users who have updated their signatures after July 2005 are reportedly not affected. Update your anti-virus signatures to ensure the vulnerability has been addressed. VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2005-2937 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. VIII.
