Debian have fixed a security bug in tigervnc which is in universe,

Debian have fixed this by building tigervnc 1.13.1 with xorg-server-source
= 2:21.1.10, but Ubuntu 23.10 has tigervnc 1.12.0+dfsg-8 and
xorg-server-source
2:21.1.7-3ubuntu2.6
On a good day I can build a .deb from source, but I am not familiar with
debdiffs and it is not clear to me that changing the upstream version
(either for mantic or noble) is a casual thing to do.
What is the next step to get this fix published ?
If all that's necessary is to rebuild tigervnc against a properly patched
xorg-xserver-source, this shouldn't be too tricky. The versions of
xorg-xserver with the patch fixed can be seen at
https://ubuntu.com/security/notices/USN-5986-1. All that would then be
necessary is to bump the dependency to require a version of
xorg-xserver-source greater than or equal to the corresponding version in
each stable release, and bump the dependency to require the newest available
version of xorg-server-source or greater in the development release.
The tricky part here is following the whole Stable Release Updates process
(https://wiki.ubuntu.com/StableReleaseUpdates), which takes at least a week
(probably more like a week and a couple of days) and requires lot of effort
and testing to make work. If you're interested in helping to fix this
hands-on, I'd be happy to assist, but stable release updates are one of the
harder parts of Ubuntu development. If you'd prefer, I'd also be happy to
just take this bug and work on getting it fixed.
Could you take it please ? I don't have any Ubuntu developer rights.
What is the best way to watch or see what you have done ?
Thanks,
