Integer overflow in GD Graphics Library libgd 2.0.28 (libgd2), and possibly other versions, allows 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, a different set of vulnerabilities than CVE-2004-0941.

Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function, a different set of vulnerabilities than CVE-2004-0990.
