gst-plugins-bad1.0: Multiple out-of-bounds read vulnerabilities were found in GStreamer's pcapparse element
CVE-2026-52721 is fixed in 10 products on 1 platform, first by DEBIAN-CVE-2026-52721, released June 15, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
