2) NULL pointer dereference

EUVDB-ID: #VU16079

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2013-7327

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error when the gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 does not check return value. A remote attacker can trigger NULL pointer dereference via invalid imagecrop arguments and cause the service to crash.

4) Heap-based buffer overflow

EUVDB-ID: #VU16066

Risk: Medium

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-7226

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in the gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9. A remote attacker can use an imagecrop function call with a large x dimension value to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
