Security Advisory Description

Description

Following are descriptions of various PHP gdImageCrop vulnerabilities:

• CVE-2013-7226

Integer overflow in the gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an imagecrop function call with a large x dimension value, leading to a heap-based buffer overflow.

• CVE-2013-7327

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.

• CVE-2013-7328

Multiple integer signedness errors in the gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 allow remote attackers to cause a denial of service (application crash) or obtain sensitive information via an imagecrop function call with a negative value for the (1) x or (2) y dimension.
