An update of the ImageMagick package has been released.

The remote host has a version of ImageMagick installed that is prior to 6.9.13-40 or 7.1.2-15. It is, therefore, affected by multiple vulnerabilities as referenced in multiple GitHub Security Advisories.

  - A heap-based buffer overflow vulnerability exists in the SUN image decoder. When processing a     specially crafted SUN image file, a signed integer overflow can occur in the ReadSUNImage function     during the calculation of the memory size for sun_pixels. On 32-bit systems and builds, the addition     of pixels_length and image->rows can wrap around, leading to the allocation of a buffer significantly     smaller than required. Subsequent decoding operations then write pixel data past the end of this     allocated buffer, resulting in a heap-based buffer overflow. This can be exploited to cause a crash     (DoS) or potentially lead to memory corruption. (CVE-2026-25897)

  - A path traversal vulnerability exists in ImageMagick's core security policy engine. The security     engine evaluates the raw filename string (the input provided by the user) before the operating system     resolves the final path. Consequently, a policy intended to block access to /etc/* can be bypassed     using standard path traversal techniques (e.g., images/../../etc/passwd). The policy matcher only sees     the unnormalized path and allows it, but the OS resolves the dots and opens the sensitive file. This     effectively nullifies security configurations like policy-secure.xml. (CVE-2026-25965)

  - A heap-based buffer overflow vulnerability exists in the WriteUHDRImage function which uses 32-bit     int arithmetic to calculate the size of the required pixel buffer. When processing images with     extremely large dimensions, the multiplication operation overflows. This results in an undersized heap     allocation. Subsequent writing of image data into this too-small buffer leads to an out-of-bounds     write. While primarily a crash risk (DoS), memory corruption of this type can, in specific     environments, be leveraged for remote code execution. (CVE-2026-25794)

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6158 advisory.

    Multiple security vulnerabilities were discovered in imagemagick, a     software suite used for editing and manipulating digital images, which     could lead to information leaks, bypass of security policies, denial of     service or arbitrary code execution.

    For the stable distribution (trixie), these problems have been fixed in     version 8:7.1.1.43+dfsg1-1+deb13u6.

    We recommend that you upgrade your imagemagick packages.

Tenable has extracted the preceding description block directly from the SUSE 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.
    `WriteUHDRImage` in `coders/uhdr.c` uses `int` arithmetic to compute the pixel buffer size. Prior to     version 7.1.2-15, when image dimensions are large, the multiplication overflows 32-bit `int`, causing an     undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially     lead to an out of bounds heap write. Version 7.1.2-15 contains a patch. (CVE-2026-25794)

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