DESCRIPTION:
Reaction Information Security has discovered a vulnerability in
XnView, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to an error when processing JPEG-LS
(lossless compression) images and can be exploited to cause a
heap-based buffer overflow via a specially crafted file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a malicious file.

The vulnerability is confirmed in version 1.99.1. Other versions may
also be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
Joseph Sheridan, Reaction Information Security.
