CVE-2010-2101: The (1) strip_tags, (2) setcookie, (3) strtok, (4) wordwrap, (5) str_word_count, and (6) str_pad functions...

Security readout for executives and security teams

This is an old PHP information-disclosure flaw. In affected PHP 5.2 and early 5.3 releases, several common string and cookie functions could leak process memory when interrupted in a specific runtime context. Business risk is mainly in legacy PHP applications that still process untrusted input on unsupported runtimes. Exposure is most likely on legacy servers, appliances, or vendor-managed applications still running PHP 5.2.x or PHP 5.3.0 through 5.3.2. Modern PHP deployments should not be affected by the described version range. Treat this as a legacy-platform cleanup item unless affected PHP versions are externally exposed or handle sensitive data. If present in production, prioritize upgrade or retirement because unsupported PHP increases broader operational risk beyond this CVE. Mitigation focus: Inventory and retire PHP 5.2.x and PHP 5.3.0 through 5.3.2 deployments.; Apply supported PHP packages from the relevant operating system or application vendor.; Check HP and SUSE advisories if those vendor packages are in scope..
