User Rating:      How can I rate this item?
Posted by Joe Shakespeare   
Debian "infamous41md" discovered a problem in libtiff, the Tag Image File Format library for processing TIFF graphics files. Upon reading a TIFF file it is possible to allocate a zero sized buffer and write to it which would lead to the execution of arbitrary code.

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

Package        : tiff
Vulnerability  : insufficient input validation
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-1308

"infamous41md" discovered a problem in libtiff, the Tag Image File
Format library for processing TIFF graphics files.  Upon reading a
TIFF file it is possible to allocate a zero sized buffer and write to
it which would lead to the execution of arbitrary code.

For the stable distribution (woody) this problem has been fixed in
version 3.5.5-6woody2.

For the unstable distribution (sid) this problem has been fixed in
version 3.6.1-4.

We recommend that you upgrade your libtiff packages immediately.


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.
