Language:

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.

Solution

Apply the relevant Junos software release or workaround referenced in Juniper advisory JSA10649.
