critical Nessus Plugin ID 298077
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1383 advisory.ImageMagick is free and open-source software used for editing and manipulating digital images. Versions prior to 7.1.2-13 have a stack overflow via infinite recursion in MSL (Magick Scripting Language) `<write>` command when writing to MSL format. Version 7.1.2-13 fixes the issue. (CVE-2026-23874)
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. (CVE-2026-23876)
NULL pointer dereference in MSL (Magick Scripting Language) parser when processing <comment> tag before any image is loaded. (CVE-2026-23952)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update ImageMagick --releasever 2023.10.20260202' or or 'dnf update --advisory ALAS2023-2026-1383 --releasever 2023.10.20260202' to update your system.See Also
