Summary
Security update for compat-openssl097g

Notes

Title of the patch
Security update for compat-openssl097g
Description of the patch
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)
