CVE-2026-80101: Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: gimp (Debian:14) 3.2.6-1; gimp (openSUSE:Leap 16.0) 3.0.8-bp160.9.1; gimp (openSUSE:Tumbleweed) 3.2.6-1.1.

Low priority for now. Upgrade to gimp (Debian:14) 3.2.6-1; gimp (openSUSE:Leap 16.0) 3.0.8-bp160.9.1; gimp (openSUSE:Tumbleweed) 3.2.6-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.
