Name of the Vulnerable Software and Affected Versions OpenSSL versions 0.9.8f through 0.9.8g

Description A double free vulnerability in OpenSSL, when TLS server name extensions are enabled, allows remote attackers to cause a denial of service (crash) via a malformed Client Hello packet. This issue can be exploited remotely, potentially leading to disruption of protected information.
