Description:
Stefan Esser has reported a vulnerability in the NetBSD -current implementation of the systrace utility and in a FreeBSD port by Vladimir Kotal, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a missing superuser check within the exit code. This can reportedly be exploited in combination with certain behaviour in the kernel's "syscall_fancy()" function to gain root privileges.
