Is Tumbleweed covered in one of those categories so it's remediated?

My TW installation, with all current updates applied, has ghostscript 9.56.1-4.1 which is vulnerable based on my (admittedly limited) understanding of this CVE.
Comment 11 Marcus Meissner 2023-07-14 06:56:20 UTC 
Factory submits turn into Tumbleweed fixes.

You can check here:
  https://www.suse.com/security/cve/CVE-2023-36664.html

The version 9.56.1-4.1 is the fixed version for tumbleweed.

Comment 15 Till Dörges 2023-07-17 12:22:50 UTC 
For lack of a better place:

LibreOffice and other applications that are also shipped with openSUSE Leap/SLE are mentioned as a potential attack vector for this vulnerability.

Does the fix from this ticket also mitigate/close these attack vectors?

Thanks!
Comment 16 Marcus Meissner 2023-07-17 12:30:01 UTC 
As LibreOffice does not contain ghostscript copies but call into system ghostscript, they are fixed by the ghostscript system updates referenced here.
Comment 34 Carlos López 2024-02-22 14:45:44 UTC 
Done, closing.
