"The version of ImageMagick installed on the remote host is prior to 6.9.10.97-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2026-3373 advisory.

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-49 and 7.1.2-24, a crafted MVG file could result in a stack overflow due to a missing
    depth or visited-set check. This issue has been patched in versions 6.9.13-49 and 7.1.2-24.
    (CVE-2026-48734)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-48 and 7.1.2-24, a missing check of a return value could lead to a heap buffer over-write
    in the MAT decoder on 32-bit systems. This issue has been patched in versions 6.9.13-48 and 7.1.2-24.
    (CVE-2026-48994)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-48 and 7.1.2-24, a missing check in the DCM decoder could result in an image with invalid
    dimensions and that could cause crashes in other operation. This issue has been patched in versions
    6.9.13-48 and 7.1.2-24. (CVE-2026-49218)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-50 and 7.1.2-25, a missing check for maximum memory request in AcquireAlignedMemory could
    trigger an out-of-Memory condition. This issue has been patched in versions 6.9.13-50 and 7.1.2-25.
    (CVE-2026-53460)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-50 and 7.1.2-25, when an allocation fails in CheckPrimitiveExtent this can result in a
    heap-use-after-free and result in a crash. This issue has been patched in versions 6.9.13-50 and 7.1.2-25.
    (CVE-2026-53462)

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-50 and 7.1.2-25, when passing incorrect arguments in the distort operation a null pointer
    deference will occur. This issue has been patched in versions 6.9.13-50 and 7.1.2-25. (CVE-2026-53463)
