SUSE SLES11 Security Update : openssl (SUSE-SU-2018:2207-1)

Medium Nessus Plugin ID 111575

Synopsis

The remote SUSE host is missing one or more security updates.

Description

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)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
