Package : openssl1.0
Version : 1.0.2u-1~deb9u2
CVE ID : CVE-2020-1968
Robert Merget, Marcus Brinkmann, Nimrod Aviram, and Juraj Somorovsky
discovered that certain Diffie-Hellman ciphersuites in the TLS
specification and implemented by OpenSSL contained a flaw. A remote
attacker could possibly use this issue to eavesdrop on encrypted
communications. This was fixed in this update by disabling the insecure
ciphersuites.
For Debian 9 stretch, this problem has been fixed in version
1.0.2u-1~deb9u2.
We recommend that you upgrade your openssl1.0 packages.
For the detailed security status of openssl1.0 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/openssl1.0
