Package : imagemagick Version : 8:6.9.11.60+dfsg-1.3+deb11u9 CVE ID : CVE-2026-23874 CVE-2026-23876 CVE-2026-23952 Debian Bug : 1126075 1126076 1126077

imagemagick, a image processing suite, was affected by multiple vulnerabilities

CVE-2026-23874

A stack overflow via infinite recursion was found in MSL (Magick Scripting Language) `<write>` command when writing to MSL format

CVE-2026-23876

A heap buffer overflow vulnerability was found in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file.
Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines

CVE-2026-23952

A NULL pointer dereference vulnerability was found in the MSL (Magick Scripting Language) parser when processing <comment> tags before images are loaded. This can lead to DoS attack (Deny of Service)

For Debian 11 bullseye, these problems have been fixed in version 8:6.9.11.60+dfsg-1.3+deb11u9.

We recommend that you upgrade your imagemagick packages.
