User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu It was discovered that the GnuTLS certificate verification methods implemented in Curl did not check for expiration and activation dates. When performing validations, tools using libcurl3-gnutls would incorrectly allow connections to sites using expired certificates.
=========================================================== 
Ubuntu Security Notice USN-484-1              July 17, 2007
curl vulnerability
CVE-2007-3564
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libcurl3-gnutls                          7.15.1-1ubuntu2.1

Ubuntu 6.10:
  libcurl3-gnutls                          7.15.4-1ubuntu2.2

Ubuntu 7.04:
  libcurl3-gnutls                          7.15.5-1ubuntu2.1

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

It was discovered that the GnuTLS certificate verification methods
