In mpc8_read_header in libavformat/mpc8.c in Libav 12.3, an input file can result in an avio_seek infinite loop and hang, with 100% CPU consumption. Attackers could leverage this vulnerability to cause a denial of service via a crafted file.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
