TITLE:
libpng Uninitialised Pointer Arrays Vulnerability

SECUNIA ADVISORY ID:
SA33970

VERIFY ADVISORY:
http://secunia.com/advisories/33970/

DESCRIPTION:
A vulnerability has been reported in libpng, which can be exploited
by malicious people to cause a DoS (Denial of Service) or to
potentially compromise an application using the library.

The vulnerability is caused due to the library improperly
initialising certain pointer arrays prior to freeing array elements
in case the application runs out of memory. This can potentially be
exploited to cause a memory corruption via a specially crafted PNG
file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in versions prior to 1.0.43 and 1.2.35.

SOLUTION:
Update to version 1.0.43 or 1.2.35.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Tavis Ormandy.
