Description

 BSD contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when the rcvtty component fails to properly drop SGID privileges before executing arbitrary commands contained within incoming messages. A malicious user can prepare a shell script containing the commands, which will execute with the privileges of the tty group. This flaw may lead to a loss of integrity.
