Package        : libexif
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-0664
Debian Bug     : 298464

Sylvain Defresne discovered a buffer overflow in libexif, a library
that parses EXIF files (such as JPEG files with extra tags).  This bug
could be exploited to crash the application and maybe to execute
arbitrary code as well.

For the stable distribution (woody) this problem has been fixed in
version 0.5.0-1woody1.

For the unstable distribution (sid) this problem has been fixed in
version 0.6.9-5.

We recommend that you upgrade your libexif 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.
