Debian Security Advisory DSA-1643-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
October 05, 2008 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : feta
Vulnerability : insecure temp file handling
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2008-4440
Debian Bug : 496397

Dmitry E. Oboukhov discovered that the "to-upgrade" plugin of Feta,
a simpler interface to APT, dpkg, and other Debian package tools
creates temporary files insecurely, which may lead to local denial
of service through symlink attacks.

For the stable distribution (etch), this problem has been fixed in
version 1.4.15+etch1.

For the unstable distribution (sid), this problem has been fixed in
version 1.4.16+nmu1.

We recommend that you upgrade your feta 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
