Heap-based buffer overflow in Kaspersky Anti-Virus Engine, as used in Kaspersky Personal 5.0.227, Anti-Virus On-Demand Scanner for Linux 5.0.5, and F-Secure Anti-Virus for Linux 4.50 allows remote attackers to execute arbitrary code via a crafted CHM file.

Unquoted Windows search path vulnerability in Kaspersky Anti-Virus 5.0 might allow local users to gain privileges via a malicious "program.exe" file in the C: folder.

Multiple interpretation error in Kaspersky 5.0.372 allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Multiple interpretation error in unspecified versions of Kaspersky Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.

Heap-based buffer overflow in Kaspersky Antivirus (KAV) 5.0 and Kaspersky Personal Security Suite 1.1 allows remote attackers to execute arbitrary code via a CAB file with large records after the header.

Kaspersky Anti-Virus for Unix/Linux File Servers 5.0-5 uses world-writable permissions for the (1) log and (2) license directory, which allows local users to delete log files, append to arbitrary files via a symlink attack on kavmonitor.log, or delete license keys and prevent keepup2date from properly executing.

The klif.sys driver in Kaspersky Labs Anti-Virus 5.0.227, 5.0.228, and 5.0.335 on Windows 2000 allows local users to gain privileges by modifying certain critical code addresses that are later accessed by privileged programs.

Sophos Anti-Virus before 3.87.0, and Sophos Anti-Virus for Windows 95, 98, and Me before 3.88.0, 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.

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.

Computer Associates (CA) InoculateIT 6.0, eTrust Antivirus r6.0 through r7.1, eTrust Antivirus for the Gateway r7.0 and r7.1, eTrust Secure Content Manager, eTrust Intrusion Detection, EZ-Armor 2.0 through 2.4, and EZ-Antivirus 6.1 through 6.3 allow 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.
