Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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).
Update the affected packages.
