Description Andrej Nemec 2018-02-21 13:02:28 UTC

The mad_decoder_run() function in decoder.c in Underbit libmad through 0.15.1b allows attackers to cause a denial of service (SIGABRT because of double free or corruption) or possibly have unspecified other impact via a crafted file. NOTE: this may overlap CVE-2017-11552.
