Announcement ID: openSUSE-SU-2018:1906-1 Rating: moderate References: #1097158 #1097624 #1098592 Cross-References: CVE-2018-0732 Affected Products: openSUSE Leap 42.3 ______________________________________________________________________________
An update that solves one vulnerability and has two fixes is now available.
This update for openssl fixes the following issues:
- CVE-2018-0732: During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server could have sent a very large prime value to the client. This caused 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 could be exploited in a Denial Of Service attack (bsc#1097158). - Blinding enhancements for ECDSA and DSA (bsc#1097624, bsc#1098592)
