Affected is the function type1_callsubr of the file devices/vector/gdevpsfx.c of the component Pdfwrite. The manipulation leads to stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. Upgrading to version 10.08.0 is able to address this issue. It is suggested to upgrade the affected component. A solution was implemented: \"I've chosen to fix this slightly differently by using the defined macro in the font parsing loop rather than in the callsubr function, because this better matches the pattern of 'normal' usage.\"\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7 · updated 2026-10-19 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-103226.json)\n- **RHSA-2026:83551** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-10-15 · [advisory](https://access.redhat.com/errata/RHSA-2026:83551)\n- **RHSA-2026:83552** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8) · released 2026-10-15 · [advisory](https://access.redhat.com/errata/RHSA-2026:83552)\n- **RHSA-2026:83553** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9), Red Hat Enterprise Linux CodeReady Linux Builder (v. 9) · released 2026-10-15 · [advisory](https://access.redhat.com/errata/RHSA-2026:83553)","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":34.7,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
