ALAS2023-2026-1851


Amazon Linux 2023 Security Advisory: ALAS2023-2026-1851
Advisory Released Date: 2026-06-22
Advisory Updated Date: 2026-06-22
Severity: Important

Issue Overview:

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. (CVE-2026-10118)
