CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:

SOFTWARE:
BMV 1.x

DESCRIPTION:
felinemenace has reported a vulnerability in BMV, which potentially
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in the
"openpsfile()" function when allocating memory to store the file
offsets of each page in a PS file. This can be exploited to cause a
heap corruption, which may allow arbitrary code execution via a
specially crafted PS file.

Successful exploitation requires that the user is e.g. tricked into
opening a malicious PS file.

The vulnerability has been reported in version 1.2. Other versions
may also be affected.

SOLUTION:
Do not use BMV to open PS files from untrusted sources.
