GnuPG VS-Desktop 3.1.22

GnuPG VS-Desktop® version 3.1.22 is available since 2022-05-03. The previous version was 3.1.21.

Notes to Admins

A bug (CVE-2018-25032) in the underlying zlib library might have enabled an attack if the attacker was able to control the data that was to be encrypted with GnuPG VS-Desktop.

There are no known attacks through this vector, but it is still important to update to 3.1.22. Especially if data for encryption originates from untrustworthy sources. (T5910)
