Ubuntu 12.04 LTS : linux vulnerabilities (USN-3338-1)

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

Synopsis :

The remote Ubuntu host is missing one or more security-related

Description :

It was discovered that the stack guard page for processes in the Linux
kernel was not sufficiently large enough to prevent overlapping with
the heap. An attacker could leverage this with another vulnerability
to execute arbitrary code and gain administrative privileges

Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling 32
bit compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A
local unprivileged attacker could use this to cause a denial of
service (system crash) or execute arbitrary code with administrative
privileges. (CVE-2016-4997).

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 packages. Note that the updated package may not be
immediately available from the package repository and its mirrors.

Risk factor :

High / CVSS Base Score : 7.2
CVSS Temporal Score : 6.0
Public Exploit Available : true
