Buffer overflow in the getauthfromURL function in httpget.c in mpg123 pre0.59s and mpg123 0.59r could allow remote attackers or local users to execute arbitrary code via an mp3 file that contains a long string before the @ (at sign) in a URL.
Buffer overflow in the find_next_file function in playlist.c for mpg123 0.59r allows remote attackers to execute arbitrary code via a crafted MP3 playlist.
Buffer overflow in layer2.c in mpg123 0.59r and possibly mpg123 0.59s allows remote attackers to execute arbitrary code via a certain (1) mp3 or (2) mp2 file.
mpg123 0.59r allows remote attackers to cause a denial of service and possibly execute arbitrary code via an MP3 file with a zero bitrate, which creates a negative frame size.
