This flaw occurs when the `fcTL` width exceeds the `IHDR` width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the `load_layer()` function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution.\n\n## Affected\n\n- `enterprise_linux = 9.0`\n- `enterprise_linux_eus = 9.6`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:73768** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6) · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73768)\n- **RHSA-2026:50817** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9) · released 2026-08-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:50817)","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":40.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
