Package: libvorbis
Version: 1.3.4-2
Severity: normal
While investigating the cause for #772978, the relevant libvorbis code
gave me the impression that (with input files different from the
referenced one) the division by zero may happen even if oggdec handled
the reported errors correctly.
The relevant stacktrace:
Process terminating with default action of
signal 8 (SIGFPE)
Integer divide by zero at address 0x802FA8133
at 0x50632A6: res2_inverse (res0.c:830)
by 0x50654A8: mapping0_inverse (mapping0.c:756)
by 0x5054071: vorbis_synthesis (synthesis.c:88)
by 0x4E3AC66: _fetch_and_process_packet
(vorbisfile.c:707)
by 0x4E3E073: ov_read_filter (vorbisfile.c:1971)
by 0x4E3E6D2: ov_read (vorbisfile.c:2092)
by 0x40212A: decode_file (oggdec.c:304)
by 0x402692: main (oggdec.c:455)
I am going to look for other ways (not exploiting oggdec's poor error
handling) to trigger this division by zero and report it back here.
Cheers,
Martin
