Mac OS X 10.6 computers can't connect to ASA w/ AnyConnect 2.5.3041

[cclem]

Due to the recent security issue with AnyConnect 2.5.2019, the ASA pushed AnyConnect 2.5.3041 to the all of the Windows and Mac computers. After the upgrade, some of the Mac OS X computers can't establish a VPN session when using the new client. Downgrading the client to 2.5.2019 resolves the issue.

Is anyone else seeing a similar issue with this release of AnyConnect?

After pushing 2.5.3, did you remove it from the ASA? If so, you're probably running into:

CSCth83069    API fails to launch cached Downloader

The bug details don't mention this but this only causes a problem when the Downloader (which is part of the .pkg file) on the ASA is older than the one cached on the client. The bug is in Resolved state but the fix has not been released yet.

If the ASA still has 2.5.3 configured, then the above bug does not applie. In that case I'd suggest to check the Anyconnect event log, and/or open a TAC case.
