CVE-2006-7230: Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memo...

Security readout for executives and security teams

This is an old PCRE library flaw that can crash software when it compiles specially crafted regular expressions. The business impact is denial of service, not data theft, based on the supplied record. Exposure is most likely in legacy systems or embedded products still using PCRE before 7.0. Systems are exposed if they run PCRE before 7.0, including older Linux distribution packages or products embedding that library. Risk is highest where users, tenants, or integrations can supply regular expressions that applications compile. Treat as a legacy resilience issue. Prioritize internet-facing or multi-tenant services that accept user-defined regex. Broad emergency response is not supported by the supplied evidence, but outdated PCRE should be removed from supported environments. Mitigation focus: Inventory PCRE versions in operating systems, containers, appliances, and bundled application dependencies.; Apply vendor security updates from the relevant distribution or product advisory.; Upgrade affected PCRE deployments to a fixed, vendor-supported version not before 7.0..
