DESCRIPTION:
Mauro Olea 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 certain
MBM (MultiBitMap) files, which can be exploited to cause a heap-based
buffer overflow by e.g. tricking a user into opening a specially
crafted MBM file.

The vulnerability is confirmed in version 1.97.4. Prior versions may
also be affected.

SOLUTION:
Update to version 1.97.5.

PROVIDED AND/OR DISCOVERED BY:
