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. (CVE-2019-1547)
Matt Caswell discovered that OpenSSL incorrectly handled the random number
generator (RNG). 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)
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)
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. (CVE-2019-1563)
