CVE-2017-12839

Estado: ModificadaAlta (8.3)—

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.
