Symptoms

f5fpc -s -t https://<hostname>:<port> is not working f5fpc -s -x -t https://<hostname>:<port> is working When we trigger "f5fpc -s -t https://<hostname>:<port>" on linux console we see "free() double free detected in tcache 2"

Impact

Edge Client running on Linux is unable to connect to VPN.

Conditions

When we trigger "f5fpc -s -t https://<hostname>:<port>" on linux console we see "free() double free detected in tcache 2".

Workaround

Use f5fpc -s -x -t https://<hostname>:<port> which avoid server certificate authentication, but not suggested as this will be security concern.

Fix Information

Fix is made to make sure Linux CLI client server certificate validation works. f5fpc -s -t https://<hostname>:<port> is working. Previously, Linux cli client would not get connected to VPN if server certificate validation is needed. So it was required to specify the -x flag to bypass server certificate validation f5fpc -s -x -t https://<hostname>:<port> Now it is fixed.
