Hi, The following vulnerability was published for poppler. CVE-2026-93653[0]: | A denial of service flaw was found in Poppler's Splash backend. A | crafted PDF with tiling-pattern geometry approaching the int32 | boundary can cause SplashOutputDev::tilingPatternFill to compute an | attacker-controlled repeat count that drives an excessively long | loop in the pattern-fill scanline routine, without a corresponding | memory allocation. An attacker could exploit this by supplying a | malicious PDF to an application that renders it via Poppler's Splash | backend, causing the rendering process to consume 100% CPU for an | attacker-controlled, extended duration. While checking I have not found a reported upstream issue, but might have missed it so far the only reference was the Bugzilla entry from Red Hat, [1]. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
