Description Wade Mealing 2021-01-18 00:08:56 UTC 
A flaw was found in the gstreamer parsing code in the function gst_h264_slice_parse_dec_ref_pic_marking.  An attacker able to trigger this section of code can cause a buffer overflow possibly overflowing the element on the stack leading to memory corruption.
