Integer overflow in the create_bits function in pixman-bits-image.c in Pixman before 0.32.6 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via large height and stride values.

Vincent LE GARREC discovered an integer overflow in pixman, a pixel-manipulation library for X and cairo. A remote attacker can exploit this flaw to cause an application using the pixman library to crash, or potentially, to execute arbitrary code with the privileges of the user running the application.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2918-1 advisory.
