From Red Hat Security Advisory 2006:0663 :

Updated ncompress packages that address a security issue and fix bugs are now available.

This update has been rated as having low security impact by the Red Hat Security Response Team.

The ncompress package contains file compression and decompression utilities, which are compatible with the original UNIX compress utility (.Z file extensions).

Tavis Ormandy of the Google Security Team discovered a lack of bounds checking in ncompress. An attacker could create a carefully crafted file that could execute arbitrary code if uncompressed by a victim.
(CVE-2006-1168)

In addition, two bugs that affected Red Hat Enterprise Linux 4 ncompress packages were fixed :

* The display statistics and compression results in verbose mode were not shown when operating on zero length files.

* An attempt to compress zero length files resulted in an unexpected return code.

Users of ncompress are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0308 advisory.

    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 cp command wrongly returned the exit code 0 to     indicate success if a device ran out of space while attempting to 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Note: udhcpc is not used on Scientific 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.

  - 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.

  - Prior to this update, the msh shell did not support the     'set -o pipefail' command. This update adds support for     this command.

  - 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.

  - 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.

Lack of bounds checking in the decompression routine could result in a heap buffer underflow. Attackers could potentially exploit this to execute arbitrary code by tricking users into decompressing a specially crafted archive. (CVE-2006-1168)
