Ubuntu Security Notice 4504-1 - 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 removing the insecure ciphersuites from OpenSSL. Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys. This issue only affected Ubuntu 18.04 LTS. Various other issues were also addressed.

An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys. Matt Caswell discovered that OpenSSL incorrectly handled the random number generator. This may result in applications that use the fork system call sharing the same RNG state between the parent and the child, contrary to expectations. This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.10.

1e3a91bc1f9dfce01af26026f856e064eab4c8ee0a8f457b5ae30b40b8b711f2OpenSSL Security Advisory 20190910 - Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. Other issues were also addressed.
