Description Martin Prpič 2015-01-21 12:47:09 UTC
An integer overflow flaw, leading to an out-of-bounds memory read, was found in the way the oggenc utility, which is used to encode audio into the Ogg Vorbis format, processed certain WAV files. An attacker could provide a specially crafted WAV file that would crash oggenc when processed.

I am not able to reproduce the crash on x86_64 using vorbis-tools-1.4.0-18.fc21 and attachment #983303 [details].  Valgrind output is sane:

$ rpm -q vorbis-tools

$ curl -JO 'https://bugzilla.redhat.com/attachment.cgi?id=983303'
curl: Saved to filename 'crash_ex.wav'

$ valgrind oggenc -r -o test.ogg ./crash_ex.wav

Thanks for the hint!  I should not have used the -r option.  My mistake.
