Hi, The following vulnerability was published for imagemagick. CVE-2026-23876[0]: | ImageMagick is free and open-source software used for editing and | manipulating digital images. Prior to versions 7.1.2-13 and | 6.9.13-38, a heap buffer overflow vulnerability 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. Versions 7.1.2-13 and 6.9.13-38 fix the | issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
