CVE-2014-2523 CVE-2103-2929
Several vulnerabilities have been discovered in the Linux kernel that may lead
to a denial of service, information leak or privilege escalation. The Common
Vulnerabilities and Exposures project identifies the following problems:
CVE-2013-0343
George Kargiotakis reported an issue in the temporary address handling
of the IPv6 privacy extensions. Users on the same LAN can cause a denial
of service or obtain access to sensitive information by sending router
advertisement messages that cause temporary address generation to be
disabled.
CVE-2013-2147
Dan Carpenter reported issues in the cpqarray driver for Compaq
Smart2 Controllers and the cciss driver for HP Smart Array controllers
allowing users to gain access to sensitive kernel memory.
CVE-2013-2889
Kees Cook discovered missing input sanitization in the HID driver for
Zeroplus game pads that could lead to a local denial of service.
CVE-2013-2893
Kees Cook discovered that missing input sanitization in the HID driver
for various Logitech force feedback devices could lead to a local denial
of service.
CVE-2013-2929
Vasily Kulikov discovered that a flaw in the get_dumpable() function of
the ptrace subsytsem could lead to information disclosure. Only systems
with the fs.suid_dumpable sysctl set to a non-default value of '2' are
vulnerable.
CVE-2013-4162
Hannes Frederic Sowa discovered that incorrect handling of IPv6 sockets
using the UDP_CORK option could result in denial of service.
CVE-2013-4299
Fujitsu reported an issue in the device-mapper subsystem. Local users
could gain access to sensitive kernel memory.
CVE-2013-4345
Stephan Mueller found in bug in the ANSI pseudo random number generator
which could lead to the use of less entropy than expected.
CVE-2013-4512
Nico Golde and Fabian Yamaguchi reported an issue in the user mode
linux port. A buffer overflow condition exists in the write method
for the /proc/exitcode file. Local users with sufficient privileges
allowing them to write to this file could gain further elevated
privileges.
CVE-2013-4587
Andrew Honig of Google reported an issue in the KVM virtualization
subsystem. A local user could gain elevated privileges by passing
a large vcpu_id parameter.
CVE-2013-6367
Andrew Honig of Google reported an issue in the KVM virtualization
subsystem. A divide-by-zero condition could allow a guest user to
cause a denial of service on the host (crash).
CVE-2013-6380
Mahesh Rajashekhara reported an issue in the aacraid driver for storage
products from various vendors. Local users with CAP_SYS_ADMIN privileges
could gain further elevated privileges.
CVE-2013-6381
Nico Golde and Fabian Yamaguchi reported an issue in the Gigabit Ethernet
device support for s390 systems. Local users could cause a denial of
service or gain elevated privileges via the SIOC_QETH_ADP_SET_SNMP_CONTROL
ioctl.
CVE-2013-6382
Nico Golde and Fabian Yamaguchi reported an issue in the XFS filesystem.
Local users with CAP_SYS_ADMIN privileges could gain further elevated
privileges.
CVE-2013-6383
Dan Carpenter reported an issue in the aacraid driver for storage devices
from various vendors. A local user could gain elevated privileges due to
a missing privilege level check in the aac_compat_ioctl function.
CVE-2013-7263 CVE-2013-7264 CVE-2013-7265
mpb reported an information leak in the recvfrom, recvmmsg and recvmsg
system calls. A local user could obtain access to sensitive kernel memory.
CVE-2013-7339
Sasha Levin reported an issue in the RDS network protocol over Infiniband.
A local user could cause a denial of service condition.
CVE-2014-0101
Nokia Siemens Networks reported an issue in the SCTP network protocol
subsystem. Remote users could cause a denial of service (NULL pointer
dereference).
CVE-2014-1444
Salva Peiro reported an issue in the FarSync WAN driver. Local users
with the CAP_NET_ADMIN capability could gain access to sensitive kernel
memory.
CVE-2014-1445
Salva Peiro reported an issue in the wanXL serial card driver. Local
users could gain access to sensitive kernel memory.
CVE-2014-1446
Salva Peiro reported an issue in the YAM radio modem driver. Local users
with the CAP_NET_ADMIN capability could gain access to sensitive kernel
memory.
CVE-2014-1874
Matthew Thode reported an issue in the SELinux subsystem. A local user
with CAP_MAC_ADMIN privileges could cause a denial of service by setting
an empty security context on a file.
CVE-2014-2039
Martin Schwidefsky reported an issue on s390 systems. A local user
could cause a denial of service (kernel oops) by executing an application
with a linkage stack instruction.
CVE-2014-2523
Daniel Borkmann provided a fix for an issue in the nf_conntrack_dccp
module. Remote users could cause a denial of service (system crash)
or potentially gain elevated privileges.
For the oldstable distribution (squeeze), this problem has been fixed in
version 2.6.32-48squeeze5.
The following matrix lists additional source packages that were rebuilt for
compatibility with or to take advantage of this update:
Debian 6.0 (squeeze)
user-mode-linux 2.6.32-1um-4+48squeeze5
We recommend that you upgrade your linux-2.6 and user-mode-linux packages.
Note: Debian carefully tracks all known security issues across every
linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, updates for lower priority issues will normally not
be released for all kernels at the same time. Rather, they will be
released in a staggered or "leap-frog" fashion.
