Amazon Linux 2023 : ImageMagick, ImageMagick-c++, ImageMagick-c++-devel (ALAS2023-2026-1550)

medium Nessus Plugin ID 306201

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1550 advisory.

 ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-18 and 6.9.13-43, an out-of-bounds write of a zero byte exists in the X11 `display` interaction path that could lead to a crash. Versions 7.1.2-18 and 6.9.13-43 patch the issue. (CVE-2026-33535)

 ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-18 and 6.9.13-43, due to an incorrect return value on certain platforms a pointer is incremented past the end of a buffer that is on the stack and that could result in an out of bounds write. Versions 7.1.2-18 and 6.9.13-43 patch the issue. (CVE-2026-33536)

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 2023.11.20260413' or or 'dnf update --advisory ALAS2023-2026-1550 --releasever 2023.11.20260413' to update your system.
