CVE-2026-78475: Gimp: unbounded stack vla and 21-byte stack over-read in pix (esm) loader

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.26% (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:13) 3.0.4-3+deb13u11; gimp (Debian:14) 3.2.6-1; gimp (openSUSE:Leap 16.0) 3.0.8-bp160.9.1.

Low priority for now. Upgrade to gimp (Debian:13) 3.0.4-3+deb13u11; gimp (Debian:14) 3.2.6-1; gimp (openSUSE:Leap 16.0) 3.0.8-bp160.9.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.
