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.
