CVE-2022-2719

Description

From CVE.org

In ImageMagick, a crafted file could trigger an assertion failure when a call to WriteImages was made in MagickWand/operation.c, due to a NULL image list. This could potentially cause a denial of service. This was fixed in upstream ImageMagick version 7.1.0-30.

Statement

This flaw is out of support scope for ImageMagick shipped in Red Hat Enterprise Linux 6 and 7. Please see https://access.redhat.com/support/policy/updates/errata/ for more info on support scope.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

CWE-617

Availability

Technical Impact: DoS: Crash, Exit, or Restart

An attacker that can trigger an assert statement can still lead to a denial of service if the relevant code can be triggered by an attacker, and if the scope of the assert() extends beyond the attacker's own session.

Red Hat would like to thank Vinay Rohila for reporting this issue.
