Debian have fixed a security bug in tigervnc which is in universe,
so someone needs to generate a debdiff for the security team to

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 ?
Just watch the bug report you filed, you'll probably get email
notifications about it. I'll assign to myself so I'm less likely to forget.
Thanks for letting us know about this!
Thanks,
