Junos OS: OpenSSL Security Advisories [16 Apr 2018] and [12 June 2018] (JSA10919)

Medium Nessus Plugin ID 121069

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According 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).
(CVE-2018-0732)
- 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)

Solution

Apply the relevant Junos software release referenced in Juniper
