Debian Security Advisory DSA-1333                                         Steve Kemp
July 18th, 2007
- - ------------------------------------------------------------------------

Package        : libcurl3-gnutls
Vulnerability  : input validation
Problem type   : local and remote
Debian-specific: no
CVE Id(s)      : CVE-2007-3564

It has been discovered that the GnuTLS certificate verification methods
implemented in libcurl-gnutls, a solid, usable, and portable multi-protocol
file transfer library, did not check for expired or invalid dates.

For the stable distribution (etch), this problem has been fixed in
version 7.15.5-1etch1.

We recommend that you upgrade your libcurl3-gnutls 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

        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
