Hello, If local user privilege escalation and/or DoS is an issue for you then you may wish to ensure your kernel is not vulnerable to: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3547 "Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname." http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3621 "net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket." amongst others. Updates were recently pushed out to Debian and I assume others.
