OpenSSL has been updated to fix several security issues :

  • Avoid the openssl CRIME attack by disabling SSL compression by default. Setting the environment variable ‘OPENSSL_NO_DEFAULT_ZLIB’ to ‘no’ enables compression again. (CVE-2012-4929)

  • Timing attacks against TLS could be used by physically local attackers to gain access to transmitted plain text or private keymaterial. This issue is also known as the ‘Lucky-13’ issue. (CVE-2013-0169)

  • A OCSP invalid key denial of service issue was fixed.
    (CVE-2013-0166)
