TITLE:
Debian update for kernel-patch-vserver / util-vserver

SECUNIA ADVISORY ID:
SA19339

VERIFY ADVISORY:
http://secunia.com/advisories/19339/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
Local system

OPERATING SYSTEM:
Debian GNU/Linux unstable alias sid
http://secunia.com/product/530/
Debian GNU/Linux 3.1
http://secunia.com/product/5307/

DESCRIPTION:
Debian has issued updates for kernel-patch-vserver and util-vserver.
This fixes two security issues, which can be exploited by malicious
programs to bypass certain security restrictions.

1) The 2.4 kernel patch included in the kernel-patch-vserver package
does not properly setup the chroot barrier when used with
util-vserver. This may result in unauthorised escapes from a vserver
to the host system.

2) The default policy of util-vserver is set to trust all unknown
capabilities instead of considering them as insecure.

For more information:
SA19333

SOLUTION:
Apply updated packages.
