Use-after-free vulnerability in the CURLFile implementation in ext/curl/curl_file.c in PHP before 5.6.27 and 7.x before 7.0.12 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that is mishandled during __wakeup processing.

Security readout for executives and security teams

This vulnerability affects old PHP releases and can let a remote attacker crash a PHP process by sending crafted serialized data that PHP mishandles during CURLFile wakeup processing. The public sources also mention possible unspecified impact, but do not define it. Exposure is most likely in legacy PHP 5.6 or early PHP 7.0 deployments that include ext/curl and process attacker-influenced serialized data. Modern supported PHP versions should not be affected by the named vulnerable ranges. Treat this as a legacy-platform remediation issue. It is not KEV-listed in the supplied sources, but vulnerable PHP versions are obsolete and may carry broader operational risk beyond this CVE. Mitigation focus: Upgrade PHP to 5.6.27, 7.0.12, or later supported vendor builds.; Prefer migrating unsupported PHP branches to currently supported PHP versions.; Apply relevant distribution security updates, including Debian guidance where applicable..
