In FFmpeg 4.0.1, due to a missing check for negative values of the mquant variable, the vc1_put_blocks_clamped function in libavcodec/vc1_block.c may trigger an out-of-array access while converting a crafted AVI file to MPEG4, leading to an information disclosure or a denial of service.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In FFmpeg 4.0.1, due to a missing check for negative values of the mquant variable, the     vc1_put_blocks_clamped function in libavcodec/vc1_block.c may trigger an out-of-array access while     converting a crafted AVI file to MPEG4, leading to an information disclosure or a denial of service.
    (CVE-2018-13305)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:
