This flaw allows an attacker to achieve arbitrary code execution by tricking a user into opening a specially crafted Animated Portable Network Graphics (APNG) image. The vulnerability is caused by a stack-based buffer overflow resulting from improper validation of data length during APNG file parsing.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9 · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-92183.json)\n\n**gimp: gimp: Arbitrary code execution via stack-based buffer overflow in APNG parser** — rated Important by Red Hat.
