Gentoo Linux Security Advisory 201206-15 - Multiple vulnerabilities in libpng might allow remote attackers to execute arbitrary code or cause a Denial of Service condition. Versions less than 1.5.10 are affected.
17c59fa4ea570ff973946e70fe5303b4a6d7f8e5ec1db2b26617090a9a49954bMandriva Linux Security Advisory 2011-151 - Multiple vulnerabilities has been discovered and corrected in libpng. The png_format_buffer function in pngerror.c in libpng allows remote attackers to cause a denial of service via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. Buffer overflow in libpng, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image. Various other issues were also addressed.

The most critical one is the identified as CVE-2011-2690. Using this vulnerability, an attacker is able to overwrite memory with an arbitrary amount of data controlled by her via a crafted PNG image.
3e4ff8efb347ee8c838157bb520547cc9e35f8767d8e12ee5f0743289e6a2a10Red Hat Security Advisory 2011-1105-01 - The libpng packages contain a library of functions for creating and manipulating PNG image format files. A buffer overflow flaw was found in the way libpng processed certain PNG image files. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash or, potentially, execute arbitrary code with the privileges of the user running the application. Note: The application behavior required to exploit CVE-2011-2690 is rarely used. No application shipped with Red Hat Enterprise Linux behaves this way, for example.

If a user or automated system were tricked into opening a crafted PNG file, an attacker could cause libpng to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS, 10.10, and 11.04. It was discovered that libpng did not properly handle certain malformed PNG images. If a user or automated system were tricked into opening a crafted PNG file, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.
