Debian Security Advisory DSA-1674-1                  security@debian.org

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.


Debian GNU/Linux 4.0 alias etch
- -------------------------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
