Doc Text:
A flaw was found in GStreamer's gst-plugins-base RTCP SDES packet parser. A remote sender able to reach an active media session can supply a malformed SDES entry whose declared length exceeds the received packet. Missing bounds validation can cause the receiver to read beyond the packet buffer, potentially crashing the application or exposing a limited amount of process memory.

Description OSIDB Bzimport 2026-11-09 12:56:24 UTC
GStreamer-SA-2026-0030: Missing bounds checks while parsing RTCP SDES items and entries allow reads past the packet buffer. The packet length calculation also underestimates the total size by four bytes, weakening existing checks. A crafted RTCP packet may cause a crash, denial of service, or information disclosure. Fixed in gst-plugins-base 1.28.4.
