Ubuntu Security Notice (C) 2011 Canonical, Inc. / NASL script (C) 2011-2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

Goldwyn Rodrigues discovered that the OCFS2 filesystem did not
correctly clear memory when writing certain file holes. A local
attacker could exploit this to read uninitialized data from the disk,
leading to a loss of privacy. (CVE-2011-0463)

Timo Warns discovered that the LDM disk partition handling code did
not correctly handle certain values. By inserting a specially crafted
disk device, a local attacker could exploit this to gain root
privileges. (CVE-2011-1017)

It was discovered that the /proc filesystem did not correctly handle
permission changes when programs executed. A local attacker could
hold open files to examine details about programs running with higher
privileges, potentially increasing the chances of exploiting
additional vulnerabilities. (CVE-2011-1020)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly
clear memory. A local attacker could exploit this to read kernel
stack memory, leading to a loss of privacy. (CVE-2011-1078)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly
check that device name strings were NULL terminated. A local attacker
could exploit this to crash the system, leading to a denial of
service, or leak contents of kernel stack memory, leading to a loss
of privacy. (CVE-2011-1079)

Vasiliy Kulikov discovered that bridge network filtering did not
check that name fields were NULL terminated. A local attacker could
exploit this to leak contents of kernel stack memory, leading to a
loss of privacy. (CVE-2011-1080)

Peter Huewe discovered that the TPM device did not correctly
initialize memory. A local attacker could exploit this to read kernel
heap memory contents, leading to a loss of privacy. (CVE-2011-1160)

Vasiliy Kulikov discovered that the netfilter code did not check
certain strings copied from userspace. A local attacker with
netfilter access could exploit this to read kernel memory or crash
the system, leading to a denial of service. (CVE-2011-1170,
CVE-2011-1171, CVE-2011-1172, CVE-2011-2534)

Vasiliy Kulikov discovered that the Acorn Universal Networking driver
did not correctly initialize memory. A remote attacker could send
specially crafted traffic to read kernel stack memory, leading to a
loss of privacy. (CVE-2011-1173)

Dan Rosenberg discovered that the IRDA subsystem did not correctly
check certain field sizes. If a system was using IRDA, a remote
attacker could send specially crafted traffic to crash the system or
gain root privileges. (CVE-2011-1180)

Julien Tinnes discovered that the kernel did not correctly validate
the signal structure from tkill(). A local attacker could exploit
this to send signals to arbitrary threads, possibly bypassing
expected restrictions. (CVE-2011-1182)

Dan Rosenberg discovered that the X.25 Rose network stack did not
correctly handle certain fields. If a system was running with Rose
enabled, a remote attacker could send specially crafted traffic to
gain root privileges. (CVE-2011-1493)

Dan Rosenberg discovered that MPT devices did not correctly validate
certain values in ioctl calls. If these drivers were loaded, a local
attacker could exploit this to read arbitrary kernel memory, leading
to a loss of privacy. (CVE-2011-1494, CVE-2011-1495)

Timo Warns discovered that the GUID partition parsing routines did
not correctly validate certain structures. A local attacker with
physical access could plug in a specially crafted block device to
crash the system, leading to a denial of service. (CVE-2011-1577)

Phil Oester discovered that the network bonding system did not
correctly handle large queues. On some systems, a remote attacker
could send specially crafted traffic to crash the system, leading to
a denial of service. (CVE-2011-1581)

Tavis Ormandy discovered that the pidmap function did not correctly
handle large requests. A local attacker could exploit this to crash
the system, leading to a denial of service. (CVE-2011-1593)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver
did not correctly validate certain socket structures. If this driver
was loaded, a local attacker could crash the system, leading to a
denial of service. (CVE-2011-1598, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain
ioctl values. A local attacker with access to the video subsystem
could exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges. (CVE-2011-1745,
CVE-2011-2022)

Vasiliy Kulikov discovered that the AGP driver did not check the size
of certain memory allocations. A local attacker with access to the
video subsystem could exploit this to run the system out of memory,
leading to a denial of service. (CVE-2011-1746)

Dan Rosenberg discovered that the DCCP stack did not correctly handle
certain packet structures. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-1770)

Ben Greear discovered that CIFS did not correctly handle direct I/O.
A local attacker with access to a CIFS partition could exploit this
to crash the system, leading to a denial of service. (CVE-2011-1771)

Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not
correctly check the origin of mount points. A local attacker could
exploit this to trick the system into unmounting arbitrary mount
points, leading to a denial of service. (CVE-2011-1833)

Vasiliy Kulikov discovered that taskstats listeners were not
correctly handled. A local attacker could expoit this to exhaust
memory and CPU resources, leading to a denial of service.
(CVE-2011-2484)

It was discovered that Bluetooth l2cap and rfcomm did not correctly
initialize structures. A local attacker could exploit this to read
portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492)

Sami Liedes discovered that ext4 did not correctly handle missing
root inodes. A local attacker could trigger the mount of a specially
crafted filesystem to cause the system to crash, leading to a denial
of service. (CVE-2011-2493)

It was discovered that GFS2 did not correctly check block sizes. A
local attacker could exploit this to crash the system, leading to a
denial of service. (CVE-2011-2689)

Fernando Gont discovered that the IPv6 stack used predictable
fragment identification numbers. A remote attacker could exploit this
to exhaust network resources, leading to a denial of service.
(CVE-2011-2699)

The performance counter subsystem did not correctly handle certain
counters. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-2918)
