[USN-1167-1] Linux kernel vulnerabilities
Multiple kernel flaws have been fixed.
Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's
handling of IPv4 icmp packets. A remote user could exploit this to cause a
denial of service. (CVE-2011-1927)
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)
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)
Johan Hovold discovered that the DCCP network stack did not correctly
handle certain packet combinations. A remote attacker could send specially
crafted network traffic that would crash the system, leading to a denial of
service. (CVE-2011-1093)
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)
Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
interface. A local attacker on non-x86 systems might be able to cause a
denial of service. (CVE-2011-1476)
Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)
driver for Yamaha FM synthesizer chips. A local user can exploit this to
cause memory corruption, causing a denial of service or privilege
escalation. (CVE-2011-1477)
It was discovered that the security fix for CVE-2010-4250 introduced a
regression. A remote attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-1479)
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)
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 reported an error in the old ABI compatibility layer of ARM
kernels. A local attacker could exploit this flaw to cause a denial of
service or gain root privileges. (CVE-2011-1759)
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)
Timo Warns discovered that the EFI GUID partition table was not correctly
parsed. A physically local attacker that could insert mountable devices
could exploit this to crash the system or possibly gain root privileges.
(CVE-2011-1776)
It was discovered that an mmap() call with the MAP_PRIVATE flag on
"/dev/zero" was incorrectly handled. A local attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-2479)
Robert Swiecki discovered that mapping extensions were incorrectly handled.
A local attacker could exploit this to crash the system, leading to a
denial of service. (CVE-2011-2496)
The linux kernel did not properly account for PTE pages when deciding which
task to kill in out of memory conditions. A local, unprivileged could
exploit this flaw to cause a denial of service. (CVE-2011-2498)
A flaw was found in the b43 driver in the Linux kernel. An attacker could
use this flaw to cause a denial of service if the system has an active
wireless interface using the b43 driver. (CVE-2011-3359)
Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had
no prefixpaths. A local attacker with access to a CIFS partition could
exploit this to crash the system, leading to a denial of service.
(CVE-2011-3363)
Dan Rosenberg discovered flaws in the linux Rose (X.25 PLP) layer used by
amateur radio. A local user or a remote user on an X.25 network could
exploit these flaws to execute arbitrary code as root. (CVE-2011-4913)
