Rewterz Threat Advisory – CVE-2018-0732 – Juniper Junos OS OpenSSL Denial of Service Vulnerability

SEVERITY: Low

 

 

ANALYSIS SUMMARY

 

 

During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause 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.
