CVE-2014-3488: The SslHandler in Netty before 3.9.2 allows remote attackers to cause a denial of service (infinite loop an...

Security readout for executives and security teams

This is a remote denial-of-service issue in Netty's SSL handling. A specially crafted SSLv2Hello message can trap vulnerable Netty versions before 3.9.2 in an infinite loop, consuming CPU. The main business risk is service degradation or outage for systems exposing TLS endpoints backed by vulnerable Netty code. Exposure is most likely where applications embed Netty 3.x before 3.9.2 and accept TLS/SSL connections. Transitive dependencies and vendor-packaged Java services should be checked because the source bundle's affected-product metadata is incomplete. Treat this as a targeted availability risk. It is not described as data theft or code execution, but exposed vulnerable services could be forced into CPU exhaustion. Prioritize inventory and patching for internet-facing systems. Mitigation focus: Upgrade Netty to 3.9.2 or later where directly managed.; Apply vendor or distribution security updates for packaged Netty.; Check embedded and transitive Java dependencies for vulnerable Netty 3.x..
