oggenc in vorbis-tools 1.4.0 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a WAV file with the number of channels set to zero.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - vorbis-tools: segfault when trying to encode trivial raw input (CVE-2014-9640)

  - vorbis-tools: Invalid memory allocation in wav_open function in oggenc/audio.c (CVE-2017-11331)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - vorbis-tools: division by zero on crafted WAV file (CVE-2014-9638)

  - vorbis-tools: Invalid memory allocation in wav_open function in oggenc/audio.c (CVE-2017-11331)

  - Buffer overflow in the aiff_open function in oggenc/audio.c in vorbis-tools 1.4.0 and earlier allows     remote attackers to cause a denial of service (crash) via a crafted AIFF file. (CVE-2015-6749)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

CVE-2014-9638

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

CVE-2014-9639

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

CVE-2014-9640

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

CVE-2015-6749

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 1.4.0-1+deb7u1.

We recommend that you upgrade your vorbis-tools packages.

vorbis-tools was updated to fix several security issues.

  - A buffer overflow in aiff_open() that could be triggered     by opening prepared malicious files (CVE-2015-6749,     bsc#943795).

  - A division by zero and integer overflow by crafted WAV     files was fixed (CVE-2014-9638, CVE-2014-9639,     bnc#914439, bnc#914441).

Various issues have been fixed in Debian LTS (squeeze) for package vorbis-tools.

CVE-2014-9638

A crafted WAV file with number of channels set to 0 will cause oggenc to crash due to a division by zero issue. This issue has been fixed upstream by providing a fix for CVE-2014-9639. Reported upstream by 'zuBux'.

CVE-2014-9639

An integer overflow issue was discovered in oggenc, related to the number of channels in the input WAV file. The issue triggers an out-of-bounds memory access which causes oggenc to crash here (audio.c). Reported upstream by 'zuBux'.

The upstream fix for this has been backported to vorbis-tools in Debian LTS (squeeze).

CVE-2014-9640

Fix for a crash on closing raw input (dd if=/dev/zero bs=1 count=1 | oggenc -r - -o out.ogg). Reported upstream by 'hanno'.

The upstream fix for this has been backported to vorbis-tools in Debian LTS (squeeze).

CVE-2015-6749

Buffer overflow in the aiff_open function in oggenc/audio.c in vorbis-tools 1.4.0 and earlier allowed remote attackers to cause a denial of service (crash) via a crafted AIFF file. Reported upstream by 'pengsu'.

The upstream fix for this has been backported to vorbis-tools in Debian LTS (squeeze).
