Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

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.
