SECUNIA ADVISORY ID:
SA20976

VERIFY ADVISORY:
http://secunia.com/advisories/20976/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
GIMP 2.x
http://secunia.com/product/2922/

DESCRIPTION:
Henning Makholm has reported a vulnerability in Gimp, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise a user's system.

The vulnerability is caused due to a boundary error in the
"xcf_load_vector()" function when loading XCF files. This can be
exploited to cause a stack-based buffer overflow when a specially
crafted XCF file with a large "num_axes" value is opened.

Successful exploitation may allow arbitrary code execution.

The vulnerability has been reported for versions 2.2.11 and 2.3.9.
Other versions may also be affected.

SOLUTION:
Update to version 2.2.12.

PROVIDED AND/OR DISCOVERED BY:
