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.
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.
Due to the library=E2=80=99s OS independent design and core functionality: it is likely this vulnerability affects a substantial portion of Kaspersky=E2=80=99s gateway, server, and client antivirus enabled product lines on most platforms.
Note: Kaspersky=E2=80=99s antivirus OEM product line is a program where vendors may license the vulnerable library. The following link is a list containing some of the Kaspersky partners with products also likely affected by this vulnerability. Refer to your vendor for specifics.
