Ubuntu 16.04 LTS : iucode-tool vulnerability (USN-3186-1)

critical Nessus Plugin ID 96955

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3186-1 advisory.

It was discovered that iucode-tool incorrectly handled certain microcodes when using the -tr loader. If a user were tricked into processing a specially crafted microcode, a remote attacker could use this issue to cause iucode-tool to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected iucode-tool package.
