The CAB file parser in Dr.Web 5.0.2.03300, Trend Micro HouseCall 9.120.0.1004, Kaspersky Anti-Virus 7.0.0.125, Sophos Anti-Virus 4.61.0, Trend Micro AntiVirus 9.120.0.1004, McAfee Gateway (formerly Webwasher) 2010.1C, Emsisoft Anti-Malware 5.1.0.1, CA eTrust Vet Antivirus 36.1.8511, Antiy Labs AVL SDK 2.0.3.7, Antimalware Engine 1.1.6402.0 in Microsoft Security Essentials 2.0, Rising Antivirus 22.83.00.03, Ikarus Virus Utilities T3 Command Line Scanner 1.1.97.0, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via a CAB file with a modified coffFiles field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different CAB parser implementations.

The Gzip file parser in AVG Anti-Virus 10.0.0.1190, Bitdefender 7.2, Command Antivirus 5.2.11.5, Emsisoft Anti-Malware 5.1.0.1, F-Secure Anti-Virus 9.0.16160.0, Fortinet Antivirus 4.2.254.0, Ikarus Virus Utilities T3 Command Line Scanner 1.1.97.0, Jiangmin Antivirus 13.0.900, K7 AntiVirus 9.77.3565, Kaspersky Anti-Virus 7.0.0.125, McAfee Anti-Virus Scanning Engine 5.400.0.1158, McAfee Gateway (formerly Webwasher) 2010.1C, NOD32 Antivirus 5795, Norman Antivirus 6.06.12, Rising Antivirus 22.83.00.03, Sophos Anti-Virus 4.61.0, AVEngine 20101.3.0.103 in Symantec Endpoint Protection 11, Trend Micro AntiVirus 9.120.0.1004, Trend Micro HouseCall 9.120.0.1004, and VBA32 3.12.14.2 allows remote attackers to bypass malware detection via a .tar.gz file with multiple compressed streams.

Kaspersky Anti-Virus 5.0 (5.0.712); Antivirus Personal 5.0.x; Anti-Virus 6.0 (6.0.3.837), 7 (7.0.1.325), 2009 (8.0.0.x), and 2010 (9.0.0.463); and Internet Security 7 (7.0.1.325), 2009 (8.0.0.x), and 2010 (9.0.0.463); use weak permissions (Everyone:Full Control) for the BASES directory, which allows local users to gain SYSTEM privileges by replacing an executable or DLL with a Trojan horse.

kl1.sys in Kaspersky Anti-Virus 2010 9.0.0.463, and possibly other versions before 9.0.0.736, does not properly validate input to IOCTL 0x0022c008, which allows local users to cause a denial of service (system crash) via IOCTL requests using crafted kernel addresses that trigger memory corruption, possibly related to klavemu.kdl.

Unspecified vulnerability in Kaspersky Online Scanner 7.0 has unknown impact and attack vectors, as demonstrated by a certain module in VulnDisco Pack Professional 8.8, (1) "Kaspersky Online Antivirus Scanner 7.0 exploit (Linux)" and (2) "Kaspersky Online Antivirus Scanner 7.0 exploit (Windows)." NOTE: as of 20090909, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.

avp.exe in Kaspersky Internet Security 9.0.0.459 and Anti-Virus 9.0.0.463 allows remote attackers to cause a denial of service (CPU consumption and network connectivity loss) via an HTTP URL request that contains a large number of dot "." characters.

Unspecified vulnerability in Kaspersky Anti-Virus 2010 and Kaspersky Internet Security 2010 before Critical Fix 9.0.0.463 allows remote attackers to disable the Kaspersky application via unknown attack vectors unrelated to "an external script."

Buffer overflow in klim5.sys in Kaspersky Anti-Virus for Workstations 6.0 and Anti-Virus 2008 allows local users to gain privileges via an IOCTL 0x80052110 call.

Stack-based buffer overflow in kl1.sys in Kaspersky Anti-Virus 6.0 and 7.0 and Internet Security 6.0 and 7.0 allows local users to gain privileges via an IOCTL 0x800520e8 call.

Kaspersky Anti-Virus (KAV) and Internet Security 7.0 build 125 do not properly validate certain parameters to System Service Descriptor Table (SSDT) and Shadow SSDT function handlers, which allows local users to cause a denial of service (crash) via the (1) NtUserSendInput, (2) LoadLibraryA, (3) NtOpenProcess, (4) NtOpenThread, (5) NtTerminateProcess, (6) NtUserFindWindowEx, and (7) NtUserBuildHwndList kernel SSDT hooks in kylif.sys; the (8) NtDuplicateObject (DuplicateHandle) kernel SSDT hook; and possibly other kernel SSDT hooks. NOTE: the NtCreateSection vector is covered by CVE-2007-5043.1. NOTE: the vendor disputes that the DuplicateHandle vector is a vulnerability in their code, stating that "it is not an error in our code, but an obscure method for manipulating standard Windows routines to circumvent our self-defense mechanisms."
