Package        : openssl
Version        : 1.0.1t-1+deb8u9
CVE ID         : CVE-2018-0732 CVE-2018-0737
Debian Bug     : 895844

Two issues were discovered in OpenSSL, the Secure Sockets Layer toolkit.

CVE-2018-0732

    Denial of service by a malicious server that sends a very large
    prime value to the client during TLS handshake.

CVE-2018-0737

    Alejandro Cabrera Aldaya, Billy Brumley, Cesar Pereida Garcia and
    Luis Manuel Alvarez Tapia discovered that the OpenSSL RSA Key
    generation algorithm has been shown to be vulnerable to a cache
    timing side channel attack. An attacker with sufficient access to
    mount cache timing attacks during the RSA key generation process
    could recover the private key.

For Debian 8 "Jessie", these problems have been fixed in version
1.0.1t-1+deb8u9.

We recommend that you upgrade your openssl packages.
