TITLE:
Autonomy KeyView SDK XLS Processing Buffer Overflow

SECUNIA ADVISORY ID:
SA36422

VERIFY ADVISORY:
http://secunia.com/advisories/36422/

DESCRIPTION:
A vulnerability has been reported in Autonomy KeyView SDK, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in the
Keyview XLS viewer (xlssr.dll) when processing Shared String Table
(SST) records. This can be exploited to cause a heap-based buffer
overflow when a specially crafted XLS file is processed.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in xlssr.dll versions 8.0.0.7214,
8.5.0.8339, and 10.5.0.0. Other versions may also be affected.

SOLUTION:
Do not process untrusted XLS files. Delete the xlssr.dll library.
