Univention has promptly released patches for all “current” releases of
UCS: 3.2, 3.1, 3.0 and 2.4.
The first patch was released on 25th September, with further updates on 27th September.
If your UCS maintenance is current you will have received detailed “errata” announcement emails for each of the updates.
The 3.2 update was announced formally here:
Note the statement in the announcement about Univention (and Debian) using “dash” as the default script for shells is true in the later versions of UCS (3.x), but not for old versions like 2.4. Also note that using “dash” as the default shell for scripts helps, but individual script programmers can and do override this so it is not a full solution.
In all cases it is recommended that you apply the patches as soon as possible. Then check that the patches are installed and operating as expected.
If you did not receive the errata announcement emails you can see the core errata information here:
