AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

ImageMagick's MAT decoder has a heap buffer overflow vulnerability on 32-bit systems, potentially leading to data corruption or crashes.

Vulnerability

ImageMagick versions prior to 6.9.13-48 and 7.1.2-24 are affected by a heap buffer over-write vulnerability within the MAT decoder. This vulnerability occurs on 32-bit systems due to a missing check of a return value. [1]

Exploitation

An attacker could exploit this vulnerability by providing a specially crafted MAT image file to a vulnerable ImageMagick installation. The vulnerability is present in the MAT decoder, and exploitation does not appear to require user interaction or special privileges, making it accessible remotely. [1]

Impact

Successful exploitation of this vulnerability can lead to a heap buffer over-write, which may result in data corruption, denial of service (application crash), or potentially arbitrary code execution, depending on the specific conditions and system configuration. The scope of impact is limited to the ImageMagick process. [1]

Mitigation

This vulnerability has been patched in ImageMagick versions 6.9.13-48 and 7.1.2-24. Users are advised to update to these fixed versions or later. No workarounds are specified in the available references. [1]
