Debian Security Advisory DSA 314-1                     security@debian.org

--------------------------------------------------------------------------

Package        : atftp
Vulnerability  : buffer overflow
Problem-Type   : remote
CVE Id         : CAN-2003-0380

Rick Patel discovered that atftpd is vulnerable to a buffer overflow
when a long filename is sent to the server.  An attacker could exploit
this bug remotely to execute arbitrary code on the server.

For the stable distribution (woody), this problem has been fixed in
version 0.6.1.1.0woody1.

The old stable distribution (potato) does not contain an atftp
package.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your atftp 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 3.0 alias woody
