DESCRIPTION:
Walied Assar has discovered a vulnerability in OllyDbg, which can be
exploited by malicious people to potentially compromise a user's
system.

The vulnerability is caused due to an integer overflow error when
allocating memory based on the size of the resource directory entry.
This can be exploited to cause a heap-based buffer overflow via a
specially crafted Portable Executable (PE) file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a specially crafted file (does
not require debugging it).

The vulnerability is confirmed in version 1.10. Other versions may
also be affected.

SOLUTION:
Do not open files from untrusted sources.

PROVIDED AND/OR DISCOVERED BY:
Walied Assar
