CVE-2006-7225: Perl-Compatible Regular Expression (PCRE) library before 6.7 allows context-dependent attackers to cause a...

Security readout for executives and security teams

PCRE before 6.7 can fail when handling a specially malformed regular expression. The known impact is denial of service through an error or crash, not data theft or code execution in the provided sources. Business urgency depends on whether legacy software still accepts or processes untrusted regular expressions through old PCRE builds. Exposure is most likely in legacy applications, appliances, or Linux distribution packages that embed PCRE before 6.7 and process attacker-controlled regex patterns. The bundle references Red Hat, SUSE, Mandriva, Avaya, OVAL, and SecurityFocus entries, but does not provide a complete affected-product list. Treat this as a legacy denial-of-service hygiene issue. It is not supported by active exploitation evidence in the bundle, but old PCRE versions in internet-facing or multi-tenant regex-processing services should be remediated during normal vulnerability management, faster if service availability is critical. Mitigation focus: Inventory PCRE versions in operating systems, appliances, and bundled application libraries.; Upgrade or backport vendor-supported PCRE fixes where vendor advisories apply.; Check Red Hat, SUSE, Mandriva, Avaya, and other vendor guidance for product-specific packages..
