"Multiple vulnerabilities was found and corrected in busybox :

The decompress function in ncompress allows remote attackers to cause
a denial of service (crash), and possibly execute arbitrary code, via
crafted data that leads to a buffer underflow (CVE-2006-1168).

A missing DHCP option checking / sanitization flaw was reported for
multiple DHCP clients. This flaw may allow DHCP server to trick DHCP
clients to set e.g. system hostname to a specially crafted value
containing shell special characters. Various scripts assume that
hostname is trusted, which may lead to code execution when hostname is
specially crafted (CVE-2011-2716).

Additionally for Mandriva Enterprise Server 5 various problems in the
ka-deploy and uClibc packages was discovered and fixed with this
advisory.

The updated packages have been patched to correct these issues.

Update :

The wrong set of packages was sent out with the MDVSA-2012:129
advisory that lacked the fix for CVE-2006-1168. This advisory provides

"From Red Hat Security Advisory 2012:0810 :

Updated busybox packages that fix two security issues and several bugs
are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

BusyBox provides a single binary that includes versions of a large
number of system commands, including a shell. This can be very useful
for recovering from certain types of system failures, particularly
those involving broken shared libraries.

A buffer underflow flaw was found in the way the uncompress utility of
BusyBox expanded certain archive files compressed using Lempel-Ziv
compression. If a user were tricked into expanding a specially crafted
archive file with uncompress, it could cause BusyBox to crash or,
potentially, execute arbitrary code with the privileges of the user
running BusyBox. (CVE-2006-1168)

The BusyBox DHCP client, udhcpc, did not sufficiently sanitize certain
options provided in DHCP server replies, such as the client hostname.
A malicious DHCP server could send such an option with a specially
crafted value to a DHCP client. If this option's value was saved on
the client system, and then later insecurely evaluated by a process
that assumes the option is trusted, it could lead to arbitrary code
execution with the privileges of that process. Note: udhcpc is not
used on Red Hat Enterprise Linux by default, and no DHCP client script
is provided with the busybox packages. (CVE-2011-2716)

This update also fixes the following bugs :

* Prior to this update, the 'findfs' command did not recognize Btrfs
partitions. As a consequence, an error message could occur when
dumping a core file. This update adds support for recognizing such
partitions so the problem no longer occurs. (BZ#751927)

* If the 'grep' command was used with the '-F' and '-i' options at the
same time, the '-i' option was ignored. As a consequence, the 'grep
-iF' command incorrectly performed a case-sensitive search instead of
an insensitive search. A patch has been applied to ensure that the
combination of the '-F' and '-i' options works as expected.
(BZ#752134)

* Prior to this update, the msh shell did not support the 'set -o
pipefail' command. This update adds support for this command.
(BZ#782018)

* Previously, the msh shell could terminate unexpectedly with a
segmentation fault when attempting to execute an empty command as a
result of variable substitution (for example msh -c
'$nonexistent_variable'). With this update, msh has been modified to
correctly interpret such commands and no longer crashes in this
scenario. (BZ#809092)

* Previously, the msh shell incorrectly executed empty loops. As a
consequence, msh never exited such a loop even if the loop condition
was false, which could cause scripts using the loop to become
unresponsive. With this update, msh has been modified to execute and
exit empty loops correctly, so that hangs no longer occur. (BZ#752132)

All users of busybox are advised to upgrade to these updated packages,
which contain backported patches to fix these issues."

"An updated rhev-hypervisor5 package that fixes several security issues
and various bugs is now available.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The rhev-hypervisor5 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: A subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000
network interface card. A privileged guest user in a virtual machine
whose network interface is configured to use the e1000 emulated driver
could use this flaw to crash the host or, possibly, escalate their
privileges on the host. (CVE-2012-0029)

A divide-by-zero flaw was found in the Linux kernel's
igmp_heard_query() function. An attacker able to send certain IGMP
(Internet Group Management Protocol) packets to a target system could
use this flaw to cause a denial of service. (CVE-2012-0207)

A double free flaw was discovered in the policy checking code in
OpenSSL. A remote attacker could use this flaw to crash an application
that uses OpenSSL by providing an X.509 certificate that has specially
crafted policy extension data. (CVE-2011-4109)

An information leak flaw was found in the SSL 3.0 protocol
implementation in OpenSSL. Incorrect initialization of SSL record
padding bytes could cause an SSL client or server to send a limited
amount of possibly sensitive data to its SSL peer via the encrypted
connection. (CVE-2011-4576)

It was discovered that OpenSSL did not limit the number of TLS/SSL
handshake restarts required to support Server Gated Cryptography. A
remote attacker could use this flaw to make a TLS/SSL server using
OpenSSL consume an excessive amount of CPU by continuously restarting
the handshake. (CVE-2011-4619)

Red Hat would like to thank Nicolae Mogoreanu for reporting
CVE-2012-0029, and Simon McVittie for reporting CVE-2012-0207.

This updated package provides updated components that include fixes
for various security issues. These issues have no security impact on
Red Hat Enterprise Virtualization Hypervisor itself, however. The
security fixes included in this update address the following CVE
numbers :

CVE-2006-1168 and CVE-2011-2716 (busybox issues)

CVE-2009-5029, CVE-2009-5064, CVE-2010-0830 and CVE-2011-1089 (glibc
issues)

CVE-2011-1083, CVE-2011-3638, CVE-2011-4086, CVE-2011-4127 and
CVE-2012-0028 (kernel issues)

CVE-2011-1526 (krb5 issue)

CVE-2011-4347 (kvm issue)

CVE-2010-4008, CVE-2011-0216, CVE-2011-2834, CVE-2011-3905,
CVE-2011-3919 and CVE-2011-1944 (libxml2 issues)

CVE-2011-1749 (nfs-utils issue)

CVE-2011-4108 (openssl issue)

CVE-2011-0010 (sudo issue)

copy files of more than 4 gigabytes. This update modifies BusyBox, so
that in such situations, the exit code 1 is returned. Now, the cp
command shows correctly whether a process failed. (BZ#689659)

* Prior to this update, the findfs command failed to check all
existing block devices on a system with thousands of block device
nodes in '/dev/'. This update modifies BusyBox so that findfs checks
all block devices even in this case. (BZ#756723)

All users of busybox are advised to upgrade to these updated packages,
which correct these issues."

"Updated busybox packages that fix two security issues and several bugs
are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

BusyBox provides a single binary that includes versions of a large
number of system commands, including a shell. This can be very useful
for recovering from certain types of system failures, particularly
those involving broken shared libraries.

A buffer underflow flaw was found in the way the uncompress utility of
BusyBox expanded certain archive files compressed using Lempel-Ziv
compression. If a user were tricked into expanding a specially crafted
archive file with uncompress, it could cause BusyBox to crash or,
potentially, execute arbitrary code with the privileges of the user
running BusyBox. (CVE-2006-1168)

The BusyBox DHCP client, udhcpc, did not sufficiently sanitize certain
options provided in DHCP server replies, such as the client hostname.
A malicious DHCP server could send such an option with a specially
crafted value to a DHCP client. If this option's value was saved on
the client system, and then later insecurely evaluated by a process
that assumes the option is trusted, it could lead to arbitrary code
execution with the privileges of that process. Note: udhcpc is not
used on Red Hat Enterprise Linux by default, and no DHCP client script
is provided with the busybox packages. (CVE-2011-2716)

This update also fixes the following bugs :

* Prior to this update, the 'findfs' command did not recognize Btrfs
partitions. As a consequence, an error message could occur when
dumping a core file. This update adds support for recognizing such
partitions so the problem no longer occurs. (BZ#751927)

* If the 'grep' command was used with the '-F' and '-i' options at the
same time, the '-i' option was ignored. As a consequence, the 'grep
-iF' command incorrectly performed a case-sensitive search instead of
an insensitive search. A patch has been applied to ensure that the
combination of the '-F' and '-i' options works as expected.
(BZ#752134)

* Prior to this update, the msh shell did not support the 'set -o
pipefail' command. This update adds support for this command.
(BZ#782018)

* Previously, the msh shell could terminate unexpectedly with a
segmentation fault when attempting to execute an empty command as a
result of variable substitution (for example msh -c
'$nonexistent_variable'). With this update, msh has been modified to
correctly interpret such commands and no longer crashes in this
scenario. (BZ#809092)

* Previously, the msh shell incorrectly executed empty loops. As a
consequence, msh never exited such a loop even if the loop condition
was false, which could cause scripts using the loop to become
unresponsive. With this update, msh has been modified to execute and
exit empty loops correctly, so that hangs no longer occur. (BZ#752132)

All users of busybox are advised to upgrade to these updated packages,
which contain backported patches to fix these issues."
