Scientific Linux Security Update : openssl on SL5.x i386/x86_64

Medium Nessus Plugin ID 77215

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was discovered that the OBJ_obj2txt() function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. (CVE-2014-3508)

Multiple flaws were discovered in the way OpenSSL handled DTLS packets. A remote attacker could use these flaws to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory. (CVE-2014-0221, CVE-2014-3505, CVE-2014-3506)

A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman (DH) key exchange.
A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled. (CVE-2014-3510)

For the update to take effect, all services linked to the OpenSSL library (such as httpd and other SSL-enabled services) must be restarted or the system rebooted.

Solution

Update the affected packages.
