In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, the openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP interpreter, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an OpenSSL documentation omission.

Security readout for executives and security teams

CVE-2017-11144 is a PHP OpenSSL extension bug that can crash the PHP interpreter when affected PEM sealing logic fails. The main business risk is service disruption for applications still running old PHP versions and using the vulnerable OpenSSL path. Exposure is most likely on legacy PHP deployments using the openssl extension, especially code paths involving PEM sealing. Current supported PHP runtimes should not be affected by the versions listed in the CVE description. Treat as a legacy-platform remediation item. It is not KEV-listed in the supplied data, but vulnerable PHP versions are old and may indicate broader unsupported-runtime risk. Prioritize exposed services and regulated environments. Mitigation focus: Upgrade PHP to 5.6.31, 7.0.21, 7.1.7, or later supported releases.; Apply vendor-supported packages from Debian, Red Hat, NetApp, or your platform vendor.; Inventory systems running PHP with the openssl extension enabled..
