script_tag(name:"insight", value:"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 ...
