Mandriva Linux Security Advisory MDKSA-2006-113: Integer overflows were reported in the GD Graphics Library (libgd) 2.0.28, and possibly other versions. These overflows allow remote attackers to cause a denial of service and possibly execute arbitrary code via PNG image files with large image rows values that lead to a heap-based buffer overflow in the gdImageCreateFromPngCtx() function. Tetex contains an embedded copy of the GD library code.
