Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management error (CVE-ID: CVE-2011-3210)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages from clients, which allows remote attackers to cause a denial of service (daemon crash) via out-of-order messages that violate the TLS protocol.
Remediation
Install update from vendor's website.
