The following CVEs are assigned: CVE-2026-4151.
AI Analysis
Technical Summary
CVE-2026-4151 is an integer overflow vulnerability in the ANI file parser of GIMP. The vulnerability occurs due to insufficient validation of user input, which can cause an integer overflow during buffer allocation. This flaw enables remote attackers to execute arbitrary code within the context of the GIMP process if a user opens a crafted ANI file or visits a malicious page. The vulnerability has a CVSS score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). GIMP has issued an official patch to remediate this vulnerability.
Potential Impact
Successful exploitation allows remote code execution with the privileges of the user running GIMP. This can lead to full compromise of the affected system or user environment. User interaction is required, limiting exploitation to scenarios where a user opens a malicious ANI file or visits a malicious webpage. The vulnerability impacts confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
An official patch is available from GIMP to correct this vulnerability. Users and administrators should apply the update provided at https://gitlab.gnome.org/GNOME/gimp/-/commit/09e5459de913172fc51da3bd6b6adc533acd368e as soon as possible to mitigate the risk. No additional vendor-recommended mitigations are noted.
