Kaspersky Antivirus 5.0.5 and 5.5.3 allows remote attackers to cause a denial of service (CPU and memory consumption) via unknown attack vectors.

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.

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.
