Kaspersky Antivirus Remote Heap Overflow



Date
October 3, 2005

Vulnerability
The Kaspersky Antivirus Library provides file format support for virus 
analysis. During analysis of cab files Kaspersky is vulnerable to a heap 
overflow allowing attackers complete control of the system(s) being protected. 
This vulnerability can be exploited remotely without user interaction in 
default configurations through common protocols such as SMTP, SMB, HTTP, and 
FTP.

Impact
Successful exploitation of Kaspersky protected systems allows attackers 
unauthorized control of data and related privileges. It also provides leverage 
for further network compromise. Kaspersky Antivirus Library implementations are 
likely vulnerable in their default configuration.

Affected Products
Due to the library’s OS independent design and core functionality: it is likely 
this vulnerability affects a substantial portion of Kaspersky’s gateway, 
server, and client antivirus enabled product lines on most platforms.
