ASA Software Version Confusion

Answered Question

Per the new Cisco advisory cisco-sa-20080604-asa for PIX and ASA devices, I'm looking at some version updates on some of my ASAs. The Software Versions and Fixes portion of the advisory page at

confuses me because it shows version that have a trailing portion that doesn't correspond to the download. For example, for the Crafted TCP ACK Packet Vulnerability in the 8.0 release it's fixed in 8.0(3)10. It's that "10" at the end that's confusing, because when I go to download the software, I see only 8.0.3ED with no 10. I've had an 8.0(3) deployed--how can I tell if it's 8.0(3)10 specifically if the download page doesn't reference that trailing version?

Thanks in advance,


I have this problem too.

Easiest way would probably to do a

dir flash:

Then look for the image file, asa803-10-k8.bin.

That "10" in 8.0(3)10 is the build number, if you show version shows only 8.0(3) then it means you are running the initial release of 8.0(3) (Sort of call it the first build). Then '"Interim Releases" go like 8.0(3)2 , 8.0(3)3 ....8.0(3)10 and so on....all this is integrated in 8.0(4)

At least this is my understanding....
