    Multiple vulnerabilities have been discovered in OpenSSL, a Secure
    Sockets Layer toolkit. The Common Vulnerabilities and Exposures project
    identifies the following issues:
    
    CVE-2015-3194
    
        Loic Jonas Etienne of Qnective AG discovered that the signature
        verification routines will crash with a NULL pointer dereference if
        presented with an ASN.1 signature using the RSA PSS algorithm and
        absent mask generation function parameter. A remote attacker can
        exploit this flaw to crash any certificate verification operation
        and mount a denial of service attack.
    
    CVE-2015-3195
    
        Adam Langley of Google/BoringSSL discovered that OpenSSL will leak
        memory when presented with a malformed X509_ATTRIBUTE structure.
    
    CVE-2015-3196
    
        A race condition flaw in the handling of PSK identify hints was
        discovered, potentially leading to a double free of the identify
        hint data.
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 1.0.1e-2+deb7u18.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1.0.1k-3+deb8u2.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.0.2e-1 or earlier.
    
    We recommend that you upgrade your openssl packages.
