Stack-based buffer overflow in ext/phar/tar.c in PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted TAR archive.

Security readout for executives and security teams

CVE-2016-2554 is a PHP flaw in TAR archive handling. A specially crafted TAR archive can crash an affected application and may have other unspecified effects. The clearest business risk is service disruption in systems that process untrusted archives through vulnerable PHP versions. Exposure is most likely where PHP applications, upload handlers, import pipelines, or background jobs parse TAR archives from users, partners, or external feeds while running affected PHP versions. Treat this as a patching and exposure-reduction issue, especially for public upload or import workflows. Urgency rises if vulnerable PHP services process externally supplied archives. Mitigation focus: Upgrade to PHP 5.5.32, 5.6.18, 7.0.3, or vendor-patched packages.; Prioritize internet-facing upload and archive-processing services.; Restrict untrusted TAR archive ingestion until patched..
