DSA-1011-1 kernel-patch-vserver Detailed Explanation for this Vulnerability Assessment Several vulnerabilities have been discovered in the Debian vserver support for Linux. The Common Vulnerabilities and Exposures project identifies the following problems: 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. The default policy of util-vserver is set to trust all unknown capabilities instead of considering them as insecure. The old stable distribution (woody) does not contain a kernel-patch-vserver package. For the stable distribution (sarge) this problem has been fixed in version 1.9.5.5 of kernel-patch-vserver and in version 0.30.204-5sarge3 of util-vserver. For the unstable distribution (sid) this problem has been fixed in version 2.3 of kernel-patch-vserver and in version 0.30.208-1 of util-vserver. We recommend that you upgrade your util-vserver and kernel-patch-vserver packages and build a new kernel immediately.
