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.
