Description Cathy Hu 2022-07-26 09:51:25 UTC
CVE-2022-26307

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.
