sockethandler.cpp in HTTP Antivirus Proxy (HAVP) 0.88 allows remote attackers to cause a denial of service (hang) by connecting to a non-responsive server, which triggers an infinite loop due to an uninitialized variable.

The scanning engine in F-Prot Antivirus 6.2.1 4252 allows remote attackers to cause a denial of service (infinite loop) via a malformed ZIP archive, probably related to invalid offsets.

The scanning engine before 4.4.4 in F-Prot Antivirus before 6.0.9.0 allows remote attackers to cause a denial of service (engine crash) via a CHM file with a large nb_dir value that triggers an out-of-bounds read.

Multiple unspecified vulnerabilities in the scanning engine before 4.4.4 in F-Prot Antivirus before 6.0.9.0 allow remote attackers to cause a denial of service via (1) a crafted UPX-compressed file, which triggers an engine crash; (2) a crafted Microsoft Office file, which triggers an infinite loop; or (3) an ASPack-compressed file, which triggers an engine crash.

aavmker4.sys in avast! Home and Professional 4.7 for Windows does not properly validate input to IOCTL 0xb2d60030, which allows local users to gain privileges via certain IOCTL requests.

Unspecified vulnerability in multiple F-Secure anti-virus products, including Internet Security 2006 through 2008, Anti-Virus 2006 through 2008, and others, allows remote attackers to execute arbitrary code or cause a denial of service (hang or crash) via a malformed archive that triggers an unhandled exception, as demonstrated by the PROTOS GENOME test suite for Archive Formats.

Stack-based buffer overflow in PccScan.dll before build 1451 in Trend Micro AntiVirus plus AntiSpyware 2008, Internet Security 2008, and Internet Security Pro 2008 allows user-assisted remote attackers to cause a denial of service (SfCtlCom.exe crash), and allows local users to gain privileges, via a malformed .zip archive with a long name, as demonstrated by a .zip file created via format string specifiers in a crafted .uue file.

Unspecified vulnerability in avast! 4 Home and Professional Editions before 4.7.1098 allows remote attackers to have an unknown impact via a crafted TAR archive.

arclib.dll before 7.3.0.9 in CA Anti-Virus (formerly eTrust Antivirus) 8 and certain other CA products allows remote attackers to cause a denial of service (infinite loop and loss of antivirus functionality) via an invalid "previous listing chunk number" field in a CHM file.

Stack-based buffer overflow in the Anti-Virus engine before content update 30.6 in multiple CA (formerly Computer Associates) products allows remote attackers to execute arbitrary code via a large invalid value of the coffFiles field in a .CAB file.
