| Description: | Summary:
The remote host is missing an update for the 'linux, linux-ec2' package(s) announced via the USN-1041-1 advisory.
Vulnerability Insight:
Louis Rilling and Matthieu Fertre reported a use after free error in the
Linux kernel's futex_wait function. A local user could exploit this flaw to
cause a denial of service (system crash) or possibly gain privileges via a
specially crafted application. (CVE-2014-0205)
Ben Hawkes discovered that the Linux kernel did not correctly filter
registers on 64bit kernels when performing 32bit system calls. On a 64bit
system, a local attacker could manipulate 32bit system calls to gain root
privileges. (CVE-2010-3301)
Dan Rosenberg discovered that the btrfs filesystem did not correctly
validate permissions when using the clone function. A local attacker could
overwrite the contents of file handles that were opened for append-only, or
potentially read arbitrary contents, leading to a loss of privacy.
(CVE-2010-2537, CVE-2010-2538)
Dave Chinner discovered that the XFS filesystem did not correctly order
inode lookups when exported by NFS. A remote attacker could exploit this to
read or write disk blocks that had changed file assignment or had become
unlinked, leading to a loss of privacy. (CVE-2010-2943)
Kees Cook discovered that the Intel i915 graphics driver did not correctly
validate memory regions. A local attacker with access to the video card
could read and write arbitrary kernel memory to gain root privileges.
(CVE-2010-2962)
Robert Swiecki discovered that ftrace did not correctly handle mutexes. A
local attacker could exploit this to crash the kernel, leading to a denial
of service. (CVE-2010-3079)
Dan Rosenberg discovered that several network ioctls did not clear kernel
memory correctly. A local user could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-3296, CVE-2010-3297,
CVE-2010-3298)
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)
Brad Spengler discovered that stack memory for new a process was not
correctly calculated. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-3858)
Kees Cook discovered that the ethtool interface did not correctly clear
kernel memory. A local attacker could read kernel heap memory, leading to a
loss of privacy. (CVE-2010-3861)
Kees Cook and Vasiliy Kulikov discovered that the shm interface did not
clear kernel memory correctly. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4072)
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)
James Bottomley discovered that the ICP vortex storage array controller
driver did not validate certain sizes. A local attacker on a 64bit ... [Please see the references for more information on the vulnerabilities]
