An update that solves three vulnerabilities and has two
fixes is now available.

Description:

This update for compat-openssl098 fixes the following security 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)
- CVE-2018-0737: The RSA Key generation algorithm has been shown to be
vulnerable to a cache timing side channel attack. An attacker with
sufficient access to mount cache timing attacks during the RSA key
generation process could have recovered the private key (bsc#1089039)
- CVE-2018-0739: Constructed ASN.1 types with a recursive definition (such
as can be found in PKCS7) could eventually exceed the stack given
malicious input with excessive recursion. This could have resulted in
DoS (bsc#1087102).
