Debian Marco d'Itri discovered that thttpd, a small, fast and secure webserver, makes use of insecure temporary files when its logfiles are rotated, which might lead to a denial of service through a symlink attack. The original advisory for this issue didn't contain fixed packages for all supported architectures which are corrected in this update.

Debian Bug     : 396277


Marco d'Itri discovered that thttpd, a small, fast and secure webserver,
makes use of insecure temporary files when its logfiles are rotated,
which might lead to a denial of service through a symlink attack.

The original advisory for this issue didn't contain fixed packages for all
supported architectures which are corrected in this update.

For the stable distribution (sarge) this problem has been fixed in
version 2.23beta1-3sarge2

For the unstable distribution (sid) this problem has been fixed in
version 2.23beta1-5

We recommend that you upgrade your thttpd 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.
