ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, when reading multiple images with different dimensions an out of bounds heap write can occur. This issue has been patched in versions 6.9.13-48 and 7.1.2-23.

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 Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 6.9.13-48 and 7.1.2-23, when reading multiple images with different dimensions an out of bounds     heap write can occur. This issue has been patched in versions 6.9.13-48 and 7.1.2-23. (CVE-2026-46520)

Note that Nessus relies on the presence of the package as reported by the vendor.
