CVE-2026-125040Gst-plugins-base: gst-plugins-base: quadratic regex processing in srt/webvtt subtitle parser causes denial of service

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9 Publicada: (hace 5 días)

Descripción

A flaw was found in the SRT and WebVTT subtitle parser in GStreamer's gst-plugins-base. While sanitizing inline subtitle markup, the parser repeatedly searches the remaining text with unanchored regular expressions. A crafted subtitle cue with a long line of unmatched markup-like text can force quadratic CPU use and make a GStreamer-based application unresponsive.

Debilidad (CWE): CWE-1333

A flaw was found in abrt. The completeness check introduced to mitigate CVE-2026-54228 and CVE-2026-54229 only verifies that a dump directory contains a "count" element, which an unprivileged user can create. This allows a local attacker to bypass the guard a…
