CVE-2026-66757: Gimp: signed integer overflow in file-sgi (sgi-lib) causes the plugin to crash on rle sgi images

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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-bp160.8.1, 3.0.8-bp160.7.1, 3.0.8-bp160.6.1; gimp (openSUSE:Tumbleweed) 3.2.4-3.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to gimp (Debian:14) 3.2.6-1; gimp (openSUSE:Leap 16.0) 3.0.8-bp160.8.1, 3.0.8-bp160.7.1, 3.0.8-bp160.6.1; gimp (openSUSE:Tumbleweed) 3.2.4-3.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service.
