A heap-based buffer over-read in the getbits function in src/libmpg123/getbits.h in mpg123 through 1.25.5 allows remote attackers to cause a possible denial-of-service (out-of-bounds read) or possibly have unspecified other impact via a crafted mp3 file.
Integer overflow in the INT123_parse_new_id3 function in the ID3 parser in mpg123 before 1.25.5 on 32-bit platforms allows remote attackers to cause a denial of service via a crafted file, which triggers a heap-based buffer overflow.
