Description

Multics contains a flaw that may allow a local user to elevate privileges. The issue is due to a flaw in the unlocked stack base system. It is possible for an attacker to manipulate the signaller to enter at location 0 with an invalid index register before setting the stack pointer to an area of extraneous storage in a link segment (such as emergency_shutdown.link). This could allow an attacker to place custom code in the link that would be executed with ring0 privileges.
