Package: gjay
Version: 0.2.8.3-4.1
Severity: normal
GJay segfaulted in the initial scanning phase upon reading a particular
mp3 file.
#0 0x000000000041b2a1 in header_bitrate (h=0x7fffffe89040) at mp3.c:300

startpos=3240540) at mp3.c:204
#4 0x000000000041a90f in get_mp3_info (mp3=0x7fffffe892b0, scantype=1,
fullscan_vbr=0) at mp3.c:132
It turns out that the problem is that at
int header_bitrate(mp3header *h) {
return bitrate[h->version & 1][3-h->layer][h->bitrate-1];
}
h->bitrate had the value of 0, causing an array underrun. According to
quick googling, zero is a valid value for the bitrate field in a frame
header, indicating a "free format" frame. I don't know exactly what this
means, and it may well be that the mp3 file was more or less broken.
In any case, value zero in the bitrate field should be either support or
detected and rejected.
