Ubuntu 8.04 LTS : linux vulnerabilities (USN-614-1)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2008-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that PowerPC kernels did not correctly handle
reporting certain system details. By requesting a specific set of
information, a local attacker could cause a system crash resulting in
a denial of service. (CVE-2007-6694)

A race condition was discovered between dnotify fcntl() and close() in
the kernel. If a local attacker performed malicious dnotify requests,
they could cause memory consumption leading to a denial of service, or
possibly send arbitrary signals to any process. (CVE-2008-1375)

On SMP systems, a race condition existed in fcntl(). Local attackers
could perform malicious locks, causing system crashes and leading to a
denial of service. (CVE-2008-1669)

The tehuti network driver did not correctly handle certain IO
functions. A local attacker could perform malicious requests to the
driver, potentially accessing kernel memory, leading to privilege
escalation or access to private system information. (CVE-2008-1675).

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.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
