Multiple integer signedness errors in libavcodec/dsputil.c in FFmpeg before 2.1 allow remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted data.

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.

  - qffmpeg: Invalid free in libavcodec/shorten.c due to invalid channel count (CVE-2013-0873)

  - qffmpeg: out of array write in case of realloc failure in libavcodec/parser.c (CVE-2013-7023)

  - The ff_er_frame_end function in libavcodec/error_resilience.c in FFmpeg before 1.0.4 and 1.1.x before     1.1.1 does not properly verify that a frame is fully initialized, which allows remote attackers to trigger     a NULL pointer dereference via crafted picture data. (CVE-2013-0860)

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 host is affected by the vulnerability described in GLSA-201603-06 (FFmpeg: Multiple vulnerabilities)
