Description:
A vulnerability has been reported in Kaspersky Anti-Virus, which can be exploited by malicious people to cause a DoS (Denial of Service), or compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the scan engine when parsing a malformed CHM file. This can be exploited to cause a heap-based buffer overflow when a specially crafted CHM file is scanned. On Windows platforms, the anti-virus may fail to scan any other files after a malformed CHM file has been encountered.
The vulnerability has been reported in the following versions:
* Kaspersky Personal 5.0.227
* Kaspersky Anti-Virus On-Demand Scanner for Linux 5.0.5
Other products that use the Kaspersky Anti-Virus Engine may also be affected.
Solution:
The vulnerability has reportedly been fixed via a signature update after July 2005.
