authdes_ezdecode() calls malloc() using a length provided by the
connection handshake sent by a newly connected client in order
to authenticate to the server, so should be treated as untrusted.
It didn't check if malloc() failed before writing to the newly
allocated buffer, so could lead to a server crash if the server
fails to allocate memory (up to UINT16_MAX bytes, since the len
field is a CARD16 in the X protocol).

commit 6ba44b91e37622ef8c146d8f2ac92d708a18ed34
use O_NOFOLLOW to open the existing lock file, so symbolic links
aren't followed, thus avoid revealing if it point to an existing
file.

relinquishing privileges (602_nx-X11_initgroups.full.patch).
The Fedora review of NX (redistributed) caught the following rpmlint issue:
This executable is calling setuid and setgid without setgroups or initgroups.
There is a high probability this mean it didn't relinquish all groups, and this
would be a potential security issue to be fixed. Seek POS36-C on the web for
details about the problem.
Ref POS36-C:
https://www.securecoding.cert.org/confluence/display/seccode/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges
This patch adds initgroups() calls to the code to initialize the supplemental group list.

(056_nx-X11_Werror-format-security.full.patch).
The below patch fixes more -Werror=format-security errors.
Interestingly, most of the errors only showed up on our arm builds. No
idea why.
