CVE-2022-26307: Debian Linux

High severity, CVSS 8.8. EPSS: 1.5% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 10.0 only
• Libreoffice Libreoffice: from 7.2.0, before 7.2.7 (fixed in 7.2.7); from 7.3.0, before 7.3.3 (fixed in 7.3.3)
