USN-3840-1 openssl, openssl1.0 vulnerabilities

Samuel Weiser discovered that OpenSSL incorrectly handled DSA signing. An attacker could possibly use this issue to perform a timing side-channel attack and recover private DSA keys. CVE-2018-0734 Samuel Weiser discovered that OpenSSL incorrectly handled ECDSA signing. An attacker could possibly...

Medium: openssl

Issue Overview: Libgcrypt allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA...

Amazon Linux 2 : openssl (ALAS-2018-1102)

During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...
