Package        : glibc
Problem type   : local file overwrite
Debian-specific: no

The version of GNU libc that was distributed with Debian GNU/Linux 2.2
suffered from 2 security problems:

* It was possible to use LD_PRELOAD to load libraries that are listed in
  /etc/, even for suid programs. This could be used to create
  (and overwrite) files which a user should not be allowed to.

* by using LD_PROFILE suid programs would write data to a file
  to /var/tmp, which was not done safely. Again, this could be  used
  to create (and overwrite) files which a user should not have access

Both problems have been fixed in version 2.1.3-17 and we recommend that
you upgrade your glibc packages immediately.

Please note that a side-effect of this upgrade is that ldd will no longer
work on suid programs, unless you logged in as root.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
