Medium [CVE-2026-6694] gimp file-png plugin: denial of service via oversized apng trns chunk
CVE-2026-6694Source published Source updated
A flaw was found in GIMP's file-png plugin. A remote attacker can exploit this by crafting a malicious Animated Portable Network Graphics (APNG) image containing an oversized tRNS chunk. When processing a specially crafted APNG image, the plugin may crash due to a stack buffer overflow. As GIMP executes plugins in separate processes, the main application remains unaffected, limiting the impact to the plugin's functionality. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-120. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: gimp.

- No fixed-version detail extracted. This does not mean no fix exists.
- Mitigation guidance
- To mitigate this issue, avoid opening or processing untrusted APNG (Animated Portable Network Graphics) image files with GIMP. Since the vulnerability is triggered by malformed APNG content, restricting interaction with such files will prevent the `file-png` plugin from crashing. If the plugin crashes, restarting GIMP may be necessary to restore full functionality.
