Ubuntu 16.04 LTS / 16.10 : iucode-tool vulnerability (USN-3186-1)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected iucode-tool package.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.3
(CVSS2#E:U/RL:OF/RC:C)
