Debian Security Advisory DSA 1269-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
March 18th, 2007 http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package : lookup-el
Vulnerability : insecure temporary file
Problem type : local
Debian-specific: no
CVE ID : CVE-2007-0237

Tatsuya Kinoshita discovered that Lookup, a search interface to
electronic dictionaries on emacsen, creates a temporary file in an
insecure fashion when the ndeb-binary feature is used, which allows a
local attacker to craft a symlink attack to overwrite arbitrary files.

For the stable distribution (sarge) this problem has been fixed in
version 1.4-3sarge1.

For the testing distribution (etch) this problem has been fixed in
version 1.4-5.

For the unstable distribution (sid) this problem has been fixed in
version 1.4-5.

We recommend that you upgrade your lookup-el 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 at the end of this advisory:

apt-get update
will update the internal database
apt-get upgrade

You may use an automated update by adding the resources from the
footer to the proper configuration.
