CVE-2026-10118
Poppler: integer overflow in poppler splashoutputdev::tilingpatternfill leads to heap buffer overflow via unchecked dimension multiplication
publishedCWE-190
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.
