The fix is upstream as of 3.12 and has been incorporated into the
relevant upstream stable releases as well. So as long as you're on a
relatively recent version of any currently supported kernel series this
problem should not be present (kernels prior to 3.10 were not affected
by the bug).

> 2.) Does it fix the related bug for the iwl-1000 wifi interface (part
oft my Lenovo edge e320), which has similiar symptoms on multiple access
points with the same ssid (eduroam network)?

I can't say for sure, but based on this short description I don't think
it sounds related. This issue isn't related to multiple APs with the
same SSID but rather to a small number of AP models from Netgear which
transmit some invalid data in probe response frames.

Title:
  Invalid ECSA IEs in probe response frames causes connection to drop

Status in “linux” package in Ubuntu:
  Fix Released
Status in “network-manager” package in Ubuntu:
  Invalid
Status in “network-manager” source package in Saucy:
  Invalid

Bug description:
  The connection slowly degrades until dropping.  Disabling 11n seems to
  workaround the issue.  With the last disconnect, the following
  messages were in dmesg:
