The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service (invalid pointer access and out-of-bounds read) or possibly have unspecified other impact via an incorrect boolean element in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.

Security readout for executives and security teams

This PHP flaw can let a remote attacker crash affected software that processes malicious WDDX XML. The public record names denial of service and only says other impact may be possible, without detail. Business urgency is highest for legacy PHP systems that still deserialize WDDX content from users or partners. Exposure is likely limited to legacy PHP deployments with the WDDX extension available and application paths that call wddx_deserialize on untrusted XML. Systems already running vendor-patched PHP are less likely exposed. Treat as a legacy-platform hygiene issue unless WDDX deserialization is internet-facing. Prioritize remediation on externally reachable PHP applications because reliable denial of service can still disrupt availability even without confirmed active exploitation. Mitigation focus: Upgrade PHP to 5.6.26, 7.0.11, or a vendor-patched supported package.; Apply relevant distribution advisories, including Gentoo or Red Hat packages where applicable.; Identify and reduce application use of WDDX deserialization on untrusted input..
