Oracle Linux 4 : pcre (ELSA-2007-1052)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2007:1052 :

Updated pcre packages that correct security issues are now available
for Red Hat Enterprise Linux 4 and 5.

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

[Updated 15 November 2007] Further analysis of these flaws in PCRE has
led to the single CVE identifier CVE-2006-7224 being split into three
separate identifiers and a re-analysis of the risk of each of the
flaws. We are therefore updating the text of this advisory to use the
correct CVE names for the two flaws fixed by these erratum packages,
and downgrading the security impact of this advisory from critical to
important. No changes have been made to the packages themselves.

PCRE is a Perl-compatible regular expression library.

Flaws were found in the way PCRE handles certain malformed regular
expressions. If an application linked against PCRE, such as Konqueror,
parses a malicious regular expression, it may be possible to run
arbitrary code as the user running the application. (CVE-2005-4872,
CVE-2006-7227)

Users of PCRE are advised to upgrade to these updated packages, which
contain a backported patch to correct these issues.
