Summary
ImageMagick before 7.1.2-19 contains a memory leak vulnerability in the PNG encoder when writing MNG images. Attackers can trigger the encoder failure condition to exhaust memory resources and cause denial of service.
A flaw was found in ImageMagick. This issue is categorized as a memory leak (CWE-401).
While the flaw can exhaust system memory, it requires an application to process a specially crafted MNG image, limiting the attack surface in typical Red Hat deployments. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
Weakness: CWE-401. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7.
Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: imagemagick.

Mitigation checklist
- To mitigate this use system controls (such as ulimit or container memory limits) to strictly cap the memory available to the ImageMagick process. This prevents a leak from crashing the wider system.
