-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 1011-1 security@xxxxxxxxxx http://www.debian.org/security/ Martin Schulze March 21st, 2005 http://www.debian.org/security/faq - -------------------------------------------------------------------------- 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 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. 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. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
