CVE ID         : CVE-2014-9638 CVE-2014-9639 CVE-2014-9640 CVE-2015-6749
Debian Bug     : 797461 776086 771363

vorbis-tools is vulnerable to multiple issues that can result in denial
of service.


    Divide by zero error in oggenc with a WAV file whose number of
    channels is set to zero.


    Integer overflow in oggenc via a crafted number of channels in a WAV
    file, which triggers an out-of-bounds memory access.


    Out-of bounds read in oggenc via a crafted raw file.


    Buffer overflow in the aiff_open function in oggenc/audio.c
    via a crafted AIFF file.

For Debian 7 "Wheezy", these problems have been fixed in version

We recommend that you upgrade your vorbis-tools packages.
