Junos OS: OpenSSL Security Advisories [16 Apr 2018] and [12 June 2018] (JSA10919)
Medium Nessus Plugin ID 121069
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version number, the remote Juniper Junos device is affected by a multiple vulnerabilities:
- 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. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o).
- The OpenSSL 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 recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o). (CVE-2018-0737)
