Test ID:1.3.6.1.4.1.25623.1.0.69169
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:0007
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2011:0007.

* Buffer overflow in eCryptfs. When /dev/ecryptfs has world writable
permissions (which it does not, by default, on Red Hat Enterprise Linux 6),
a local, unprivileged user could use this flaw to cause a denial of service
or possibly escalate their privileges. (CVE-2010-2492, Important)

* Integer overflow in the RDS protocol implementation could allow a local,
unprivileged user to cause a denial of service or escalate their
privileges. (CVE-2010-3865, Important)

* Missing boundary checks in the PPP over L2TP sockets implementation could
allow a local, unprivileged user to cause a denial of service or escalate
their privileges. (CVE-2010-4160, Important)

* NULL pointer dereference in the igb driver. If both Single Root I/O
Virtualization (SR-IOV) and promiscuous mode were enabled on an interface
using igb, it could result in a denial of service when a tagged VLAN packet
is received on that interface. (CVE-2010-4263, Important)

* Missing initialization flaw in the XFS file system implementation, and in
the network traffic policing implementation, could allow a local,
unprivileged user to cause an information leak. (CVE-2010-3078,
CVE-2010-3477, Moderate)

* NULL pointer dereference in the Open Sound System compatible sequencer
driver could allow a local, unprivileged user with access to /dev/sequencer
to cause a denial of service. /dev/sequencer is only accessible to root and
users in the audio group by default. (CVE-2010-3080, Moderate)

* Flaw in the ethtool IOCTL handler could allow a local user to cause an
information leak. (CVE-2010-3861, Moderate)

* Flaw in bcm_connect() in the Controller Area Network (CAN) Broadcast
Manager. On 64-bit systems, writing the socket address may overflow the
procname character array. (CVE-2010-3874, Moderate)

* Flaw in the module for monitoring the sockets of INET transport
protocols could allow a local, unprivileged user to cause a denial of
service. (CVE-2010-3880, Moderate)

* Missing boundary checks in the block layer implementation could allow a
local, unprivileged user to cause a denial of service. (CVE-2010-4162,
CVE-2010-4163, CVE-2010-4668, Moderate)

* NULL pointer dereference in the Bluetooth HCI UART driver could allow a
local, unprivileged user to cause a denial of service. (CVE-2010-4242,
Moderate)

* Flaw in the Linux kernel CPU time clocks implementation for the POSIX
clock interface could allow a local, unprivileged user to cause a denial of
service. (CVE-2010-4248, Moderate)

* Flaw in the garbage collector for AF_UNIX sockets could allow a local,
unprivileged user to trigger a denial of service. (CVE-2010-4249, Moderate)

* Missing upper bound integer check in the AIO implementation could allow a
local, unprivileged user to cause an information leak. (CVE-2010-3067, Low)

* Missing initialization flaws could lead to information leaks.
(CVE-2010-3298, CVE-2010-3876, CVE-2010-4072, CVE-2010-4073, CVE-2010-4074,
CVE-2010-4075, CVE-2010-4077, CVE-2010-4079, CVE-2010-4080, CVE-2010-4081,
CVE-2010-4082, CVE-2010-4083, CVE-2010-4158, Low)

* Missing initialization flaw in KVM could allow a privileged host user
with access to /dev/kvm to cause an information leak. (CVE-2010-4525, Low)
