Amazon Linux 2023 : ImageMagick, ImageMagick-c++, ImageMagick-c++-devel (ALAS2023-2026-1611)

high Nessus Plugin ID 311318

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1611 advisory.

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when `Magick` parses an XML file it is possible that a single zero byte is written out of the bounds. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. (CVE-2026-33899)

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, the -sample operation has an out of bounds read when an specific offset is set through the `sample:offset` define that could lead to an out of bounds read. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. (CVE-2026-33905)

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, Magick frees the memory of the XML tree via the `DestroyXMLTree()` function; however, this process is executed recursively with no depth limit imposed. When Magick processes an XML file with deeply nested structures, it will exhaust the stack memory, resulting in a Denial of Service (DoS) attack. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. (CVE-2026-33908)

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-19, a crafted image could result in an out of bounds heap write when writing a yaml or json output, resulting in a crash. This issue has been fixed in version 7.1.2-19. (CVE-2026-40169)

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions below both 7.1.2-19 and 6.9.13-44, contain a heap out-of-bounds write in the JP2 encoder with when a user specifies an invalid sampling index. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
(CVE-2026-40310)

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions below 7.1.2-19 and 6.9.13-44 contain a heap use-after-free vulnerability that can cause a crash when reading and printing values from an invalid XMP profile. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. (CVE-2026-40311)

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 2023.11.20260427' or or 'dnf update --advisory ALAS2023-2026-1611 --releasever 2023.11.20260427' to update your system.
