Debian Security Advisory DSA-1674-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
November 30, 2008 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : jailer
Vulnerability : insecure temp file generation
Debian-specific: no
CVE Id(s) : CVE-2008-5139
Debian Bug : 410548

Javier Fernandez-Sanguino Pena discovered that updatejail, a component
of the chroot maintenance tool Jailer, creates a predictable temporary
file name, which may lead to local denial of service through a symlink
attack.

For the stable distribution (etch), this problem has been fixed in
version 0.4-9+etch1.

For the upcoming stable distribution (lenny) and the unstable
distribution (sid), this problem has been fixed in version 0.4-10.

We recommend that you upgrade your jailer package.

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.
