Problem:
A vulnerability in the NSM XDB service on devices with NSM versions prior to

No other Juniper Networks products or platforms are affected by this issue.
This issue has been assigned CVE-2014-3411.
Solution:
The following software releases have been updated to resolve this specific
issue:
NSM 2012.2R8 and all subsequent releases (i.e. all releases built after
