The OpenSSL security team would like to thank Codenomicon for reporting these issues. OpenSSL Server Name extension crash - ----------------------------------- Testing using the Codenomicon TLS test suite discovered a flaw in the handling of server name extension data in OpenSSL 0.9.8f and OpenSSL 0.9.8g. If OpenSSL has been compiled using the non-default TLS server name extensions, a remote attacker could send a carefully crafted packet to a server application using OpenSSL and cause it to crash. (CVE-2008-0891). Please note this issue does not affect any other released versions of OpenSSL, and does not affect versions compiled without TLS server name extensions. Users of OpenSSL 0.9.8f or 0.9.8g should update to the OpenSSL 0.9.8h release which contains a patch to correct this issue. OpenSSL Omit Server Key Exchange message crash - ---------------------------------------------- Testing using the Codenomicon TLS test suite discovered a flaw if the 'Server Key exchange message' is omitted from a TLS handshake in OpenSSL 0.9.8f and OpenSSL 0.9.8g. If a client connects to a malicious server with particular cipher suites, the server could cause the client to crash. (CVE-2008-1672). Please note this issue does not affect any other released versions of OpenSSL. Users of OpenSSL 0.9.8f or 0.9.8g should update to the OpenSSL 0.9.8h release which contains a patch to correct this issue. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
