Package : kernel-patch-vserver, util-vserver
Vulnerability : missing attribute support
Problem type : local (remote)
Debian-specific: yes
CVE IDs : CVE-2005-4347 CVE-2005-4418
Debian Bugs : 329087 329090
Several vulnerabilities have been discovered in the Debian vserver
support for Linux. The Common Vulnerabilities and Exposures project
identifies the following problems:
CVE-2005-4347
BjЬrn 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.
CVE-2005-4418
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.
