Synopsis :

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

Description :

According to its self-reported version number, the remote Junos device
is affected by multiple vulnerabilities in the implementation of
OpenSSL :

- An error exists related to 'ec point format extension'
handling and multithreaded clients that allows freed
memory to be overwritten during a resumed session.
(CVE-2014-3509)

- An error exists related to handling fragmented
'ClientHello' messages that allows a man-in-the-middle
attacker to force usage of TLS 1.0 regardless of higher
protocol levels being supported by both the server and
the client. (CVE-2014-3511)

- A buffer overflow error exists related to handling
Secure Remote Password protocol (SRP) parameters having
unspecified impact. (CVE-2014-3512)

- A NULL pointer dereference error exists related to
handling Secure Remote Password protocol (SRP) that
allows a malicious server to crash a client, resulting
in a denial of service. (CVE-2014-5139)

Note that these issues only affects devices with J-Web or the SSL
service for JUNOScript enabled.
