The remote Scientific Linux host is missing one or more security
A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server
code. A remote attacker could possibly use this flaw to change the
ciphersuite associated with a cached session stored on the server, if
the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option,
possibly forcing the client to use a weaker ciphersuite after resuming
the session. (CVE-2010-4180, CVE-2008-7270)
Note: With this update, setting the
SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this
bug workaround can no longer be enabled.
It was discovered that OpenSSL did not always check the return value
of the bn_wexpand() function. An attacker able to trigger a memory
allocation failure in that function could possibly crash an
application using the OpenSSL library and its UBSEC hardware engine
support. (CVE-2009-3245 - SL4 Only)
For the update to take effect, all services linked to the OpenSSL
library must be restarted, or the system rebooted.
