Apache 2 before 2.0.47, when running on an IPv6 host, allows attackers to cause a denial of service (CPU consumption by infinite loop) when the FTP proxy server fails to create an IPv6 socket.

Security readout for executives and security teams

This is an old Apache 2 denial-of-service flaw. On IPv6 hosts, versions before 2.0.47 could enter an infinite CPU loop when FTP proxy socket creation failed. The likely business impact is service degradation or outage, not data theft. Exposure is mainly legacy, unpatched systems. Organizations are most likely exposed if they still run Apache 2 earlier than 2.0.47 on IPv6-enabled hosts, especially where FTP proxy functionality is present. Modern patched distributions should generally be unaffected, but legacy appliances and frozen server images deserve review. Handle during legacy exposure cleanup unless the affected host is internet-facing, business-critical, or unsupported. The issue can cause outage, but the evidence provided does not indicate data compromise or active exploitation. Mitigation focus: Upgrade Apache 2 to 2.0.47 or later, or vendor-fixed packages.; Review Red Hat and Mandriva advisories for distribution-specific packages.; Remove or disable affected FTP proxy functionality if not required..
