"The remote host has a version of ImageMagick installed that is prior to 6.9.13-43 and 7.x prior to 7.1.2-18. It is,
therefore, affected by multiple vulnerabilities:

  - 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. (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. (CVE-2026-33536)

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