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 openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21359-1 advisory.

    Changes in gimp:

    - CVE-2026-58379: Fix PSP File Parsing Heap Buffer Overflow (bsc#1270299)
    - CVE-2026-58380: Fix buffer overflow in pnmscanner_gettoken (bsc#1270444)
    - CVE-2026-58381: Prevent double-freeing PSP layer name (bsc#1270239)

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.
