Hight IOS level for 5520 with 512mb of ram?

[michaelspangenberg]

I'm looking at the recent Cisco Advisory and it indicates moving to 8.4 to fix the issues. What would be the highest code level that I would be able to go to?

Hi,

Although , the recommended RAM for the ASA 8.3+ is 2 GB , I understand that this vulnerability require upgrade to ASA 8.4 + to resolve this.

For this reason , i would recommend an upgrade to the ASA 8.4.7.23 to fix this issue.

You can also monitor the memory utilization on the ASA device after the upgrade. If it is stable , you can plan an upgrade to ASA 9.x code in future.

You would have to contact Cisco TAC to get this interim version.

Thanks and Regards,
