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. (CVE-2019-1549)</p> <p>Guido Vranken discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2019-1551)</p> <p>Bernd Edlinger discovered that OpenSSL incorrectly handled certain decryption functions. In certain scenarios, a remote attacker could possibly use this issue to perform a padding oracle attack and decrypt traffic.
