Summary

A flaw was found in Cockpit. An authenticated local user with a large user identifier (UID) can cause unauthorized modification and disclosure of login records. On 32-bit systems, an integer overflow during session accounting allows the user's login process to read or overwrite the legacy log entries of other accounts.
