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)

not correctly calculate the size of certain buffers. A local attacker
could exploit this to crash the system or possibly execute arbitrary
code as the root user. (CVE-2010-3874)

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)

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 RME Hammerfall DSP audio interface
driver did not correctly clear kernel memory. A local attacker could
exploit this to read kernel stack memory, leading to a loss of
privacy. (CVE-2010-4080, CVE-2010-4081)

clear kernel memory. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4083)

James Bottomley discovered that the ICP vortex storage array
controller driver did not validate certain sizes. A local attacker on
a 64bit system could exploit this to crash the kernel, leading to a
denial of service. (CVE-2010-4157)

Dan Rosenberg discovered multiple flaws in the X.25 facilities
parsing. If a system was using X.25, a remote attacker could exploit
this to crash the system, leading to a denial of service.
(CVE-2010-4164)

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)

Nelson Elhage discovered that the kernel did not correctly handle
process cleanup after triggering a recoverable kernel bug. If a local
attacker were able to trigger certain kinds of kernel bugs, they
could create a specially crafted process to gain root privileges.
(CVE-2010-4258)

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)

Dan Rosenberg discovered that IRDA did not correctly check the size
of buffers. On non-x86 systems, a local attacker could exploit this
to read kernel heap memory, leading to a loss of privacy.
(CVE-2010-4529)

Dan Rosenburg discovered that the CAN subsystem leaked kernel
addresses into the /proc filesystem. A local attacker could use this
to increase the chances of a successful memory corruption exploit.
(CVE-2010-4565)

Kees Cook discovered that some ethtool functions did not correctly
clear heap memory. A local attacker with CAP_NET_ADMIN privileges
could exploit this to read portions of kernel heap memory, leading to
a loss of privacy. (CVE-2010-4655)

Kees Cook discovered that the IOWarrior USB device driver did not
correctly check certain size fields. A local attacker with physical
access could plug in a specially crafted USB device to crash the
system or potentially gain root privileges. (CVE-2010-4656)

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)

Dan Carpenter discovered that the TTPCI DVB driver did not check
certain values during an ioctl. If the dvb-ttpci module was loaded, a
local attacker could exploit this to crash the system, leading to a
denial of service, or possibly gain root privileges. (CVE-2011-0521)

Jens Kuehnel discovered that the InfiniBand driver contained a race
condition. On systems using InfiniBand, a local attacker could send
specially crafted requests to crash the system, leading to a denial
of service. (CVE-2011-0695)

Dan Rosenberg discovered that XFS did not correctly initialize
memory. A local attacker could make crafted ioctl calls to leak
portions of kernel stack memory, leading to a loss of privacy.
(CVE-2011-0711)

Rafael Dominguez Vega discovered that the caiaq Native Instruments
USB driver did not correctly validate string lengths. A local
attacker with physical access could plug in a specially crafted USB
device to crash the system or potentially gain root privileges.
(CVE-2011-0712)

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)

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 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)

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)

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, CVE-2011-1747)

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-2011-1748)
