Gstreamer1-plugins-bad-free: gstreamer: multiple out-of-bounds reads in pcapparse ipv4/tcp header parsing

Assigner: redhat
Reserved: 08.06.2026 Published: 15.06.2026 Updated: 15.06.2026

Multiple out-of-bounds read vulnerabilities were found in GStreamer's pcapparse element. Malformed PCAP records can trigger reads beyond buffer boundaries during IPv4/TCP header parsing. This element is primarily used in debugging pipelines, limiting real-world exposure. A local attacker could trick a user into processing a specially crafted PCAP file, potentially leading to a crash or information disclosure.
