Subject: libvorbisfile3: segfault in ov_time_seek()
Package: libvorbisfile3
Version: 1.0.1-1
Severity: important
There is a bug in lib/vorbisfile.c in function ov_time_seek().
The variable "link" can have value -1 when is passed to expression
"vf->vi[link].rate".
This happends when the function is called with "seconds=0.0".
I would like to see sarge without this bug.
I reported this bug to upstream
http://bugs.xiph.org/show_bug.cgi?id=577
but there is no response from upstream for long time.
The same bug with "link--" can probably occurs in ov_time_seek_page(),
ov_time_tell() and ov_pcm_seek_page().
Double arithmetic is not precise, it depends on order of operands.
"for(i=0;i<links;i++) sum+=x[i]" gives slightly different result then
"for(i=links-1;i>=0;i--) sum+=x[i]".
I attached a simple test program to convince everybody that difference
of two sums is not zero.
