    Sudo: sudo: tz environment variable allows bypass of notbefore/notafter time-based authorization

    A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected.

    Sudo through 1.9.17p2 Intercept Policy Bypass via execveat

    Sudo through 1.9.17p2 fails to apply intercept policy checks to the execveat system call in ptrace-based intercept mode. Users permitted to run specific commands can execute denied programs by calling execveat directly or through fexecve, bypassing policy enforcement and logging.
