Mandriva Linux Security Advisory 2009-051 - A number of vulnerabilities have been found and corrected in libpng. Fixed 1-byte buffer overflow in pngpread.c. This was allready fixed in Mandriva Linux 2009.0. Fix the function png_check_keyword() that allowed setting arbitrary bytes in the process memory to 0. Fix a potential DoS (Denial of Service) or to potentially compromise an application using the library. The updated packages have been patched to prevent this.

Gentoo Linux Security Advisory GLSA 200812-15 - POV-Ray includes a version of libpng that might allow for the execution of arbitrary code when reading a specially crafted PNG file POV-Ray uses a statically linked copy of libpng to view and output PNG files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964, CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in POV-Ray's build system caused it to load the old version when your installed copy of libpng was >=media-libs/libpng-1.2.10. Versions less than 3.6.1-r4 are affected.
