Description:

This update for compat-openssl097g fixes the following issues:

These security issues were fixed:

- 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)
- 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)

This non-security issue was fixed:

- Fixed crash in DES_fcrypt (bsc#1065363)
