2014-01 Security Bulletin: Junos: SRX flowd crash while processing HTTP 
traffic when acting as UAC enforcer (CVE-2014-0618)

Categories:

    Junos

    SRX Series

    SIRT Advisory

Security Advisories ID: JSA10611

Last Updated: 08 Jan 2014

Version: 1.0

Product Affected:

SRX Series services gateways running Junos OS 10.4, 11.4, 12.1, or 12.1X44.

Problem:

On SRX Series services gateways acting as UAC enforcer with captive portal 
enabled, certain valid HTTP protocol messages may cause the flowd (flow 
daemon) process to crash. Repeated crashes of the flowd process represents a 
sustained denial of service condition for SRX Series devices.

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-2014-0618.

Solution:

The following software releases have been updated to resolve this specific 
issue:

All Junos OS software releases built on or after 2013-12-12, or Junos OS 
10.4R16, 11.4R8, 12.1R7, 12.1X44-D20, 12.1X45-D10, and all subsequent releases
(i.e. all releases built after 12.1X45-D10).

Customers can confirm the build date of any Junos OS release by issuing the 
command 'show version detail'.

This issue is being tracked as PR 846240 and is visible on the Customer 
Support website.

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

Workaround:

No known workaround exists for this issue.

Implementation:

How to obtain fixed software:

Security vulnerabilities in Junos are fixed in the next available Maintenance
Release of each supported Junos version. In some cases, a Maintenance Release
is not planned to be available in an appropriate time-frame. For these cases,
Service Releases are made available in order to be more timely. Security 
Advisory and Security Notices will indicate which Maintenance and Service 
Releases contain fixes for the issues described. Upon request to JTAC, 
customers will be provided download instructions for a Service Release. 
Although Juniper does not provide formal Release Note documentation for a 
Service Release, a list of "PRs fixed" can be provided on request.
