1. Systems affected:

      All versions of KDE up to and including KDE 3.0.2

2. Overview:

      KDE's SSL implementation fails to check the basic constraints on
certificates and as a result may accept certificates as valid that were signed
by an issuer who was not authorized to do so.
      
3. Impact:

      Users of Konqueror and other SSL enabled KDE software may fall victim
to a malicious man-in-the-middle attack without noticing. In such case the
user will be under the impression that there is a secure connection with a
trusted site while in fact a different site has been connected to.

4. Solution:

      Upgrade kdelibs to KDE 3.0.3. A patch for KDE 2.2.2 is available as
well for users that are unable to upgrade to KDE 3.

5. Patch:
      A patch for KDE 2.2.2 is available from 
ftp://ftp.kde.org/pub/kde/security_patches :
