How to check whether GnuPG has been fixed
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
GnuPG is the most prominent user of Libksba and it is not immediately
visible whether a fixed version of Libksba is used. To check this run:
,----
| gpgconf --show-versions
`----
and watch out for a line like
,----
| * KSBA 1.6.2 (xxxxx)
`----
If you see a version number of 1.6.2 or newer, you got the fix.
Debian fix kept the old version number 1.5.0-3, though:
