Comment: Two separate Arkeia security issues are described at the following URL:
         The newly released version 5.3.5 fixes the buffer overflow issue.
         To resolve the second issue (weak authentication of both server and
         clients) AusCERT recommends the following mitigation steps:
         1. Apply the steps in Appendix B of the Arkeia manual to restrict
            access to specific IP addresses.
         2. Add strong authentication by using either SSH tunnelling or stunnel.

Release of Arkeia Network Backup 5.3.5 fixes security issue

After carefully examining issues recently discussed in public technical forums, 
Arkeia Corp. has immediately released a new version to block any potential 
invasion of Arkeia protected networks.

ANB 5.3.5 fixes a buffer overflow bug that could allow a remote attacker to 
remotely execute arbitrary code, and thereby get root access to the machine.

The fix is also applicable to previous versions of Arkeia (5.1, 5.2, 
Arkeia Light). The appropriate packages can be found on the Arkeia websites:

    * http://www.arkeia.com/donwload/anb/ (Version 5.3.5)
    * http://www.arkeia.com/donwload/52/ (Version 5.2.28)
    * http://www.arkeia.com/donwload/51/ (Version 5.1.21) 

For Arkeia light: http://www.arkeia.org/download/light/

If you are using Arkeia in an untrusted environment such as a publicly 
accessible Web server or corporate mail gateway, it is strongly advised to 
upgrade to this version. The bug is in the arkeiad daemon process, making it 
necessary to upgrade all the sensitive client machines.

Arkeia users should also remember to take into account Arkeia security 
recommendations in the Arkeia User Manual "Appendix B: System Security." 
We urge you to read again the sections describing how to secure Arkeia 
against system-level intrusion.
