Ubuntu Security Notice 3185-1 - It was discovered that libXpm incorrectly handled certain XPM files. If a user or automated system were tricked into opening a specially crafted XPM file, a remote attacker could use this issue to cause libXpm to crash, resulting in a denial of service, or possibly execute arbitrary code.

Debian Linux Security Advisory 3772-1 - Tobias Stoeckmann discovered that the libXpm library contained two integer overflow flaws, leading to a heap out-of-bounds write, while parsing XPM extensions in a file. An attacker can provide a specially crafted XPM file that, when processed by an application using the libXpm library, would cause a denial-of-service against the application, or potentially, the execution of arbitrary code with the privileges of the user running the application.
