From Red Hat Security Advisory 2007:1068 :

Updated pcre packages that resolve several security issues are now available for Red Hat Enterprise Linux 4.

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

PCRE is a Perl-compatible regular expression library.

Flaws were discovered 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 have been possible to run arbitrary code as the user running the application.
(CVE-2006-7225, CVE-2006-7226, CVE-2006-7228, CVE-2006-7230, CVE-2007-1659)

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

Red Hat would like to thank Ludwig Nussel for reporting these issues.

Updated pcre packages that resolve several security issues are now available for Red Hat Enterprise Linux 5.

Specially crafted regular expressions could lead to a buffer overflow in the pcre library. Applications using pcre to process regular expressions from untrusted sources could therefore potentially be exploited by attackers to execute arbitrary code (CVE-2006-7224, CVE-2006-7225, CVE-2006-7226, CVE-2007-1659, CVE-2007-1660).

Multiple vulnerabilities were discovered by Tavis Ormandy and Will Drewry in the way that pcre handled certain malformed regular expressions. If an application linked against pcre, such as Konqueror, parses a malicious regular expression, it could lead to the execution of arbitrary code as the user running the application.

Updated packages have been patched to prevent this issue.
Additionally, Corporate Server 4.0 was updated to pcre version 6.7 which corrected CVE-2006-7225, CVE-2006-7226, CVE-2006-7227, CVE-2006-7228, and CVE-2006-7230.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-1059 advisory.

    [6.6-2.7]
     - Fix the names of the patches added in 6.6-2.5:
       mv pcre-6.4-posix.diff pcre-6.6-CVE-2006-7225.patch        mv pcre-6.4-fix1.patch pcre-6.6-CVE-2006-7226.patch
     - Update pcre-6.6-CVE-2007-1659.patch
     - Update pcre-6.6-CVE-2007-1660.patch
     - Add pcre-6.6-CVE-2006-7230.patch
     - Resolves: #380531

Tenable has extracted the preceding description block directly from the Oracle 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.
