Buffer overflow in GraphicsMagick

1) Buffer overflow

EUVDB-ID: #VU33245

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-14165

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c.

Mitigation

Install update from vendor's website.

Vulnerable software versions

GraphicsMagick: 1.3.26
