Ubuntu 10.10 : linux vulnerabilities (USN-1081-1)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that KVM did not correctly initialize certain CPU
registers. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-3698)

Thomas Pollet discovered that the RDS network protocol did not check
certain iovec buffers. A local attacker could exploit this to crash
the system or possibly execute arbitrary code as the root user.
(CVE-2010-3865)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation
did not correctly clear kernel memory. A local attacker could exploit
this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets
implementation did not properly initialize certain structures. A local
attacker could exploit this to read kernel stack memory, leading to a
loss of privacy. (CVE-2010-3876)

Vasiliy Kulikov discovered that the TIPC interface did not correctly
initialize certain structures. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3877)

Nelson Elhage discovered that the Linux kernel IPv4 implementation did
not properly audit certain bytecodes in netlink messages. A local
attacker could exploit this to cause the kernel to hang, leading to a
denial of service. (CVE-2010-3880)

Dan Rosenberg discovered that the ivtv V4L driver did not correctly
initialize certian structures. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4079)

Dan Rosenberg discovered that the semctl syscall did not correctly
clear kernel memory. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4083)

It was discovered that multithreaded exec did not handle CPU timers
correctly. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-4248)

Vegard Nossum discovered a leak in the kernel's inotify_init() system
call. A local, unprivileged user could exploit this to cause a denial
of service. (CVE-2010-4250)

Nelson Elhage discovered that Econet did not correctly handle AUN
packets over UDP. A local attacker could send specially crafted
traffic to crash the system, leading to a denial of service.
(CVE-2010-4342)

Tavis Ormandy discovered that the install_special_mapping function
could bypass the mmap_min_addr restriction. A local attacker could
exploit this to mmap 4096 bytes below the mmap_min_addr area, possibly
improving the chances of performing NULL pointer dereference attacks.
(CVE-2010-4346)

Dan Rosenberg discovered that the OSS subsystem did not handle name
termination correctly. A local attacker could exploit this crash the
system or gain root privileges. (CVE-2010-4527)

An error was reported in the kernel's ORiNOCO wireless driver's
handling of TKIP countermeasures. This reduces the amount of time an
attacker needs breach a wireless network using WPA+TKIP for security.
(CVE-2010-4648)

Dan Carpenter discovered that the Infiniband driver did not correctly
handle certain requests. A local user could exploit this to crash the
system or potentially gain root privileges. (CVE-2010-4649,
CVE-2011-1044)

An error was discovered in the kernel's handling of CUSE (Character
device in Userspace). A local attacker might exploit this flaw to
escalate privilege, if access to /dev/cuse has been modified to allow
non-root users. (CVE-2010-4650)

A flaw was found in the kernel's Integrity Measurement Architecture
(IMA). Changes made by an attacker might not be discovered by IMA, if
SELinux was disabled, and a new IMA rule was loaded. (CVE-2011-0006)

It was discovered that some import kernel threads can be blocked by a
user level process. An unprivileged local user could exploit this flaw
to cause a denial of service. (CVE-2011-4621).

Solution :

Update the affected packages.
