Untrusted search path vulnerability in Ghostscript 8.62 allows local users to execute arbitrary PostScript code via a Trojan horse Postscript library file in Encoding/ under the current working directory, a different vulnerability than CVE-2010-2055.

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)

It was found that Ghostscript always tried to read Ghostscript system initialization files from the current working directory before checking other directories, even if a search path that did not contain the current working directory was specified with the '-I' option, or the '-P-' option was used (to prevent the current working directory being searched first). If a user ran Ghostscript in an attacker-controlled directory containing a system initialization file, it could cause Ghostscript to execute arbitrary PostScript code.
(CVE-2010-2055)

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)

From Red Hat Security Advisory 2012:0096 :

Updated ghostscript packages that fix two security issues are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having moderate 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.
