LibreOffice supports the storage of passwords for web connections in the
user’s configuration database. The stored passwords are encrypted with a
single master key provided by the user. A flaw in LibreOffice existed where
master key was poorly encoded resulting in weakening its entropy from 128
to 43 bits making the stored passwords vulerable to a brute force attack if
an attacker has access to the users stored config. This issue affects: The
Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions
prior to 7.3.3.
