Red Hat has determined that no currently supported Red Hat products are affected by this vulnerability. Therefore, no action is required for Red Hat Enterprise Linux 10 users at this time. Users should monitor the Red Hat advisory for any updates if the assessment changes.

Description

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.
