A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:80509 advisory.

    The GIMP (GNU Image Manipulation Program) is an image composition and editing program. GIMP provides a     large image manipulation toolbox, including channel operations and layers, effects, sub-pixel imaging and     anti-aliasing, and conversions, all with multi-level undo.

    Security Fix(es):

    * gimp: GIMP APNG loader heap-buffer-overflow when fcTL width exceeds IHDR width (file-png.c)     (CVE-2026-42169)

    * gimp: gimp: Heap buffer overflow in read_channel_data() (CVE-2026-58379)

    * gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted FITS images     (CVE-2026-66758)

    * gimp: GIMP: Arbitrary code execution via crafted TIF file parsing (CVE-2026-18304)

  - A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates     memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both     values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based     buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio     subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to     arbitrary code execution or a denial of service.

    Several vulnerabilities were discovered in GIMP, the GNU Image     Manipulation Program, which could result in denial of service or     potentially the execution of arbitrary code if malformed PSP, TIFF,     DDS, PSD, SGI, FLI, FITS or ICNS files are opened.

    For the stable distribution (trixie), these problems have been fixed in     version 3.0.4-3+deb13u10.

    We recommend that you upgrade your gimp packages.
