    Description:

    OpenSSL 0.9.8k was updated to fix several security issues.

    • CVE-2015-4000: The Logjam Attack ( weakdh.org ) has been addressed by rejecting connections with DH parameters shorter than 1024 bits. We now also generate 2048-bit DH parameters by default.
    • CVE-2015-1788: Malformed ECParameters could cause an infinite loop.
    • CVE-2015-1789: An out-of-bounds read in X509_cmp_time was fixed.
    • CVE-2015-1790: A PKCS7 decoder crash with missing EnvelopedContent was fixed.
    • CVE-2015-1792: A CMS verification infinite loop when using an unknown hash function was fixed.
    • CVE-2015-1791: Fixed a race condition in NewSessionTicket creation.
    • CVE-2015-3216: Fixed a potential crash in ssleay_rand_bytes due to locking regression.
    • fixed a timing side channel in RSA decryption (bnc#929678)

    Additional changes:

    • In the default SSL cipher string EXPORT ciphers are now disabled. This will only get active if applications get rebuilt and actually use this string. (bnc#931698)
    • Added the ECC ciphersuites to the DEFAULT cipher class (bnc#879179)
