description

Red Hat Enterprise Linux 10 systems using the gstreamer1 package are affected by a memory-lifetime error in GStreamer buffer-value deserialization. An attacker may cause an application to crash when it processes untrusted caps or structure data; network-accessible GStreamer Data Protocol receivers may accept such input without user interaction.

mitigation

Restrict untrusted input to GStreamer parsers and limit network access to GStreamer Data Protocol receivers. Apply Red Hat security updates for gstreamer1 promptly when a corrected package is released.
