    Package        : openssl
    CVE ID         : CVE-2014-0160
    
    This revision to the recent OpenSSL update, DSA-2896-1, checks for some
    services that may use OpenSSL in a way that they expose the
    vulnerability.  Such services are proposed to be restarted during the
    upgrade to help in the actual deployment of the fix.
    
    The list of services that are checked is not comprehensive. For a more
    detailed check, it is recommended to use the checkrestart tool from the
    debian-goodies package. Note that client applications also need to be
    restarted.
    
    In case of doubt a full system restart is recommended.
    
    For reference, the original advisory text follows.
    
    A vulnerability has been discovered in OpenSSL's support for the
    TLS/DTLS Hearbeat extension. Up to 64KB of memory from either client or
    server can be recovered by an attacker. This vulnerability might allow
    an attacker to compromise the private key and other sensitive data in
    memory.
    
    All users are urged to upgrade their openssl packages (especially
    libssl1.0.0) and restart applications as soon as possible.
    
    According to the currently available information, private keys should be
    considered as compromised and regenerated as soon as possible. More
    details will be communicated at a later time.
    
    The oldstable distribution (squeeze) is not affected by this
    vulnerability.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.0.1e-2+deb7u6.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your openssl packages.
