    openssl regression
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 13.10
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    USN-2232-1 introduced a regression in OpenSSL.
    
    Software Description:
    - openssl: Secure Socket Layer (SSL) cryptographic library and tools
    
    Details:
    
    USN-2232-1 fixed vulnerabilities in OpenSSL. The upstream fix for
    CVE-2014-0224 caused a regression for certain applications that use
    renegotiation, such as PostgreSQL. This update fixes the problem.
    
    Original advisory details:
    
     Jüri Aedla discovered that OpenSSL incorrectly handled invalid DTLS
     fragments. A remote attacker could use this issue to cause OpenSSL to
     crash, resulting in a denial of service, or possibly execute arbitrary
     code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
     Ubuntu 14.04 LTS. (CVE-2014-0195)
      Imre Rad discovered that OpenSSL incorrectly handled DTLS recursions. A
     remote attacker could use this issue to cause OpenSSL to crash, resulting
     in a denial of service. (CVE-2014-0221)
      KIKUCHI Masashi discovered that OpenSSL incorrectly handled certain
     handshakes. A remote attacker could use this flaw to perform a
     man-in-the-middle attack and possibly decrypt and modify traffic.
     (CVE-2014-0224)
      Felix Gröbert and Ivan Fratrić discovered that OpenSSL incorrectly handled
     anonymous ECDH ciphersuites. A remote attacker could use this issue to
     cause OpenSSL to crash, resulting in a denial of service. This issue only
     affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.
     (CVE-2014-3470)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      libssl1.0.0                     1.0.1f-1ubuntu2.4
    
    Ubuntu 13.10:
      libssl1.0.0                     1.0.1e-3ubuntu1.6
    
    Ubuntu 12.04 LTS:
      libssl1.0.0                     1.0.1-4ubuntu5.16
    
    Ubuntu 10.04 LTS:
      libssl0.9.8                     0.9.8k-7ubuntu8.19
    
    After a standard system update you need to reboot your computer to make all
    the necessary changes.
