DESCRIPTION:
Marsu 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 a boundary error within the
handling of XPM files. This can be exploited to cause a stack-based
buffer overflow via a specially-crafted XPM file with an overly long
(greater than 1024 bytes) section string.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 1.90.3. Other versions may
also be affected.
SOLUTION:
Do not open untrusted XPM files.
