Public bug reported:
[Impact]
* The bump to version 11 exposed an issue of a crash with lsb_output being
broken.
* The fix avoids the segfault by validating the pointer before usage
[Test Case]
* Take a system that runs under VMWare (otherwise it will fast-path skip and
exit before the bug)
* Modify /usr/bin/lsb_release to remove e.g. the "-i" option (that would
trigger the bug)
* (re)start the vmtoolsd service/program which will crash without the fix
[Regression Potential]
* The change makes a check before accessing a (potentially bad) pointer. That
makes it every so
slightly slower but it isn't a fast path anyway. The regression risk should
therefore be rather
low. I have discussed with upstream if there also should be a strlen check,
but that was denied and we are following them on that.
[Other Info]
* We stopped releasing v11 (bug 1844834), I'll generate the uploads in a way
to have the bug 1844834 included as from a users POV it will be the first time
v11 hits -updates. Only on Eoan where it is already released the changes file
to upload will only cover the new bug.
* Removed some whitespace damage from the upstream change
