Ubuntu 10.04 LTS : linux vulnerabilities (USN-1080-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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)

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)

Krishna Gudipati discovered that the bfa adapter driver did not
correctly initialize certain structures. A local attacker could read
files in /sys to crash the system, leading to a denial of service.
(CVE-2010-4343)

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)

It was discovered that the ICMP stack did not correctly handle certain
unreachable messages. If a remote attacker were able to acquire a
socket lock, they could send specially crafted traffic that would
crash the system, leading to a denial of service. (CVE-2010-4526)

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).

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 : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 6.3
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
