Package: openconnect

Severity: normal
Tags: patch
Dear Maintainer,
when trying to use a configuration file with openconnect (--config option),
I get weird errors pointing to string corruption:
Failed to open 'tc/openconnect/vpnc-script-no-dns' for write: No such file or
directory
Inspecting the code, it seems that there is some misuse of the getopt_long
system. It assumes it is safe to use optarg for long-time storage.
The solution that works for me is an additional strdup:

As David noted, this is fixed in version 4.00 and newer. Closing as
fixed.
