Description:Summary:
The remote host is missing an update for the 'ghostscript'
package(s) announced via the referenced advisory.

Vulnerability Insight:
Ghostscript is a set of software that provides a PostScript interpreter, a
set of C procedures (the Ghostscript library, which implements the graphics
capabilities in the PostScript language) and an interpreter for Portable
Document Format (PDF) files.

An integer overflow flaw was found in Ghostscript's TrueType bytecode
interpreter. An attacker could create a specially-crafted PostScript or PDF
file that, when interpreted, could cause Ghostscript to crash or,
potentially, execute arbitrary code. (CVE-2009-3743)

Ghostscript included the current working directory in its library search
path by default. If a user ran Ghostscript without the '-P-'
option in an attacker-controlled directory containing a specially-crafted
PostScript library file, it could cause Ghostscript to execute arbitrary
PostScript code. With this update, Ghostscript no longer searches the
current working directory for library files by default. (CVE-2010-4820)

Note: The fix for CVE-2010-4820 could possibly break existing
configurations. To use the previous, vulnerable behavior, run Ghostscript
with the '-P' option (to always search the current working directory
first).

A flaw was found in the way Ghostscript interpreted PostScript Type 1 and
PostScript Type 2 font files. An attacker could create a specially-crafted
PostScript Type 1 or PostScript Type 2 font file that, when interpreted,
could cause Ghostscript to crash or, potentially, execute arbitrary code.
(CVE-2010-4054)

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

Affected Software/OS:
ghostscript on Red Hat Enterprise Linux (v. 5 server)

Solution:
Please Install the Updated Packages.
