    Synopsis
    ========
    
    A vulnerability in LibSSH can result in leakage of private key
    information.
    
    Background
    ==========
    
    LibSSH is a C library providing SSHv2 and SSHv1.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-libs/libssh              < 0.6.3                    >= 0.6.3 
    
    Description
    ===========
    
    A new connection inherits the state of the PRNG without re-seeding with
    random data.
    
    Impact
    ======
    
    Servers using ECC (ECDSA) or DSA certificates in non-deterministic mode
    may under certain conditions leak their private key.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All LibSSH users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-libs/libssh-0.6.3"
