"CVE-2018-0735 Samuel Weiser reported a timing vulnerability in the
OpenSSL ECDSA signature generation, which might leak information to
recover the private key.

CVE-2018-5407 Alejandro Cabrera Aldaya, Billy Brumley, Sohaib ul
Hassan, Cesar Pereida Garcia and Nicola Tuveri reported a
vulnerability to a timing side channel attack, which might be used to
recover the private key.

For Debian 8 'Jessie', these problems have been fixed in version
1.0.1t-1+deb8u10.

We recommend that you upgrade your openssl packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
