    Synopsis
    ========
    
    Multiple Information Disclosure vulnerabilities in OpenSSL allow
    attackers to obtain sensitive information.
    
    Background
    ==========
    
    OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
    (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
    purpose cryptography library.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  dev-libs/openssl             < 1.0.2r                  >= 1.0.2r 
    
    Description
    ===========
    
    Multiple vulnerabilities have been discovered in OpenSSL. Please review
    the CVE identifiers referenced below for details.
    
    Impact
    ======
    
    A remote attacker to obtain sensitive information, caused by the
    failure to immediately close the TCP connection after the hosts
    encounter a zero-length record with valid padding.
    
    A local attacker could run a malicious process next to legitimate
    processes using the architecture’s parallel thread running capabilities
    to leak encrypted data from the CPU's internal processes.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All OpenSSL users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.2r"
