| Description: | Summary:
The remote host is missing an update for the 'linux, linux-ec2' package(s) announced via the USN-1141-1 advisory.
Vulnerability Insight:
Brad Spengler discovered that the kernel did not correctly account for
userspace memory allocations during exec() calls. A local attacker could
exploit this to consume all system memory, leading to a denial of service.
(CVE-2010-4243)
Alexander Duyck discovered that the Intel Gigabit Ethernet driver did not
correctly handle certain configurations. If such a device was configured
without VLANs, a remote attacker could crash the system, leading to a
denial of service. (CVE-2010-4263)
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)
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 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)
Kees Cook reported that /proc/pid/stat did not correctly filter certain
memory locations. A local attacker could determine the memory layout of
processes in an attempt to increase the chances of a successful memory
corruption exploit. (CVE-2011-0726)
Timo Warns discovered that MAC partition parsing ... [Please see the references for more information on the vulnerabilities]
