PHP 5.5.x gdImageCrop Function Null Pointer Dereference Vulnerability

CVE-2013-7327 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

The gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 does not check return values, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via invalid imagecrop arguments that lead to use of a NULL pointer as a return value, a different vulnerability than CVE-2013-7226.
