EUVDB-ID: #VU33393

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-5059

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

An exploitable code execution vulnerability exists in the XPM image rendering functionality of SDL2_image 2.0.4. A specially crafted XPM image can cause an integer overflow, allocating too small of a buffer. This buffer can then be written out of bounds resulting in a heap overflow, ultimately ending in code execution. An attacker can display a specially crafted image to trigger this vulnerability.

Mitigation

Install update from vendor's website.
