2014-06 Security Bulletin: Junos Pulse Secure Access Service (SSL VPN) and 
Junos Pulse Access Control Service (UAC): Weak SSL cipher allowed unexpectedly

Security Advisories ID: 	JSA10628
Last Updated: 			11 Jun 2014	
Version: 			3.0

Product Affected:
SA700, SA2500, FIPS SA4000, SA4500, FIPS SA4500, FIPS SA6000, SA6500, FIPS

and FIPS IC6500. The affected software releases includes IVE OS: 7.4, 8.0, 
and UAC 4.4 and 5.0.

A weak cipher issue has been discovered on the Junos Pulse Secure Access 
Service (SSL VPN) and Junos Pulse Access Control Service OS devices. When 
configuring the device to use a higher level cipher setting, a lower level 
cipher was unexpectedly enabled in error. While clients should always negotiate
the use of the highest available cipher, older clients may have negotiated a 
lower and therefore less secure cipher.

Juniper SIRT is not aware of any malicious exploitation of this vulnerability.

No other Juniper Networks products or platforms are affected by this issue.

This issue has been assigned CVE-2014-3812

Software updates to IVE OS and UAC have been released to resolve this issue. 
Releases containing the fix include IVE OS 8.0r1, 7.4r5 and UAC 5.0r1 and 4.4r5
and all subsequent releases.

KB16765 - "In which releases are vulnerabilities fixed?" describes which
release vulnerabilities are fixed as per our End of Engineering and End of
