    Description

    OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)and Transport Layer Security (TLS v1) protocols, as well as afull-strength, general purpose cryptography library.A flaw was found in the way the TLS/SSL (Transport Layer Security/SecureSockets Layer) protocols handled session renegotiation. A man-in-the-middleattacker could use this flaw to prefix arbitrary plain text to a client'ssession (for example, an HTTPS connection to a website). This could forcethe server to process an attacker's request as if authenticated using thevictim's credentials. This update addresses this flaw by implementing theTLS Renegotiation Indication Extension, as defined in RFC 5746.(CVE-2009-3555)Refer to the following Knowledgebase article for additional details aboutthis flaw: http://kbase.redhat.com/faq/docs/DOC-20491All openssl097a users should upgrade to these updated packages, whichcontain a backported patch to resolve this issue. For the update to takeeffect, all services linked to the openssl097a library must be restarted,or the system rebooted.
