Description
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.
