The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2005-4347 Bjørn Steinbrink discovered that the chroot barrier is not set correctly with util-vserver which may result in unauthorised escapes from a vserver to the host system. This vulnerability is limited to the 2.4 kernel patch included in kernel-patch-vserver. The correction to this problem requires updating the util-vserver package as well and installing a new kernel built from the updated kernel-patch-vserver package.
