AI-suggested
Red Hat has released official security updates that fix this vulnerability in poppler packages for Red Hat Enterprise Linux 8 and 10. Users should apply the updates as described in Red Hat advisories RHSA-2026:24984 and RHSA-2026:24985. Detailed instructions for applying these updates are available at https://access.redhat.com/articles/11258. No additional mitigation is required if the updates are applied.
Description
A flaw was found in Poppler's Splash backend. A remote attacker could exploit this vulnerability by crafting a malicious PDF file that, when rendered, triggers an integer overflow in the `tilingPatternFill` function. This overflow leads to an undersized heap memory allocation, allowing a subsequent out-of-bounds write. Successful exploitation could result in arbitrary code execution, information disclosure, or denial of service within the context of the application processing the PDF.
