Descriptions
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.
LibreOffice admite el almacenamiento de contraseñas para conexiones web en la base de datos de configuración del usuario. Las contraseñas almacenadas son cifradas con una única clave maestra proporcionada por el usuario. Se presentaba un fallo en LibreOffice en el que la clave maestra estaba codificada inapropiadamente resultando en un debilitamiento de su entropía de 128 a 43 bits haciendo que las contraseñas almacenadas sean vulnerables a un ataque de fuerza bruta si un atacante presenta acceso a la configuración almacenada del usuario. Este problema afecta a: The Document Foundation LibreOffice versiones 7.2 anteriores a 7.2.7; versiones 7.3 anteriores a 7.3.3
