A flaw was found in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer by a single byte (CVE-2007-5135). Few applications make use of this vulnerable function and generally it is used only when applications are compiled for debugging.
A number of possible side-channel attacks were discovered affecting OpenSSL. A local attacker could possibly obtain RSA private keys being used on a system. In practice these attacks would be difficult to perform outside of a lab environment. This update contains backported patches to mitigate these issues. (CVE-2007-3108)
As well, these updated packages fix the following bugs :
multithreaded applications could cause a segmentation fault or deadlock when calling the random number generator initialization (RAND_poll) in the OpenSSL library, for a large number of threads simultaneously.
in certain circumstances, if an application using the OpenSSL library reused the SSL session cache for multiple purposes (with various parameters of the SSL protocol), the session parameters could be mismatched.
a segmentation fault could occur when a corrupted pkcs12 file was being loaded using the ‘openssl pkcs12 -in [pkcs12-file]’ command, where [pkcs12-file] is the pkcs12 file.
