Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1826 advisory.

When writing an IPTC output file a malicious input file could cause an out of bounds read of a single byte. (as per: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-7wff-wpr6-vmhm) (CVE-2026-42326)

Due to a missing check in the PSD decoder it would be possible to bypass the list-length resource policy when decoding a PSD image. Other security limits would still apply. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-cwpj-h54c-xjpx) (CVE-2026-45031)

An of by one in the meta encoder could result in an out of bounds read of a single byte in the meta encoder. (as per: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-cr6r-hmj8-pr7r) (CVE-2026-45358)

An invalid connected-components:keep-top value could result in a heap buffer over-read when performing the connected components operation (CVE-2026-45359)

When performing a polynomial distortion an out of bounds over-read of 24 bytes can occur when specifying specific arguments. (CVE-2026-45624)

Because of a missing check in the MNG coder it would be possible to read more images than the list limit policy would allow resulting in excessive resource use. (CVE-2026-45664)

When reading multiple images with different dimensions an out of bounds heap write can occur. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-36wm-hprc-mcf5) (CVE-2026-46520)

When using LZMA compression in the MIFF encoder an out of bounds write can occur due to a missing check.
(as per: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-jcqp-6r6f-3mfx) (CVE-2026-46521)

Due to a missing check in the MIFF decoder a crafted file could cause an infinite loop resulting in CPU exhaustion. (CVE-2026-46522)

A crafted MSL image can trigger a heap-use-after-free. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-5r4x-w6p5-222q) (CVE-2026-46523)

An incorrect check in the JP2 will result in an heap buffer over-write of a single byte when specifying certain options. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-533m-3wf6-c33v) (CVE-2026-46559)

An attacker who can connect to a magick -distribute-cache service can cause a heap buffer over-write in the server process. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-p93h-f2jc-477j) (CVE-2026-46692)

An attacker who can connect to a magick -distribute-cache service can hijack a file descriptor in the server process when a race condition is met. (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-4g75-9r48-jf92) (CVE-2026-46693)

The distributed pixel cache was originally designed to operate without a challenge-response authentication model. However, given today's heightened security expectations, we have changed our implementation.
(CVE-2026-47165)

An attacker who can connect to a magick -distribute-cache service can cause a heap buffer over-read in the server process (as per:
https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-6gxq-f64p-5w6f) (CVE-2026-47166)

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 2023.12.20260622' or or 'dnf update --advisory ALAS2023-2026-1826 --releasever 2023.12.20260622' to update your system.
