Debian Security Advisory DSA-1904-1                  security () debian org
http://www.debian.org/security/                      Giuseppe Iuculano
October 09, 2009                      http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package        : wget
Vulnerability  : insufficient input validation
Problem type   : remote
Debian-specific: no
Debian bug     : 549293
CVE ID         : CVE-2009-3490


Daniel Stenberg discovered that wget, a network utility to retrieve files from
the Web using http(s) and ftp, is vulnerable to the "Null Prefix Attacks Against
SSL/TLS Certificates" published at the Blackhat conference some time ago.  This
allows an attacker to perform undetected man-in-the-middle attacks via a crafted
ITU-T X.509 certificate with an injected null byte in the Common Name field.


For the oldstable distribution (etch), this problem has been fixed in
version 1.10.2-2+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 1.11.4-2+lenny1.

For the testing distribution (squeeze), this problem will be fixed soon.

For the  unstable distribution (sid), this problem has been fixed in
version 1.12-1.


We recommend that you upgrade your wget packages.


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.
