1. Systems affected: All versions of KDE up to KDE 3.2.3 inclusive. 2. Overview: WESTPOINT internet reconnaissance services alerted the KDE security team that the KDE web browser Konqueror allows websites to set cookies for certain country specific secondary top level domains. 3. Impact: Web sites operating under the affected domains can set HTTP cookies in such a way that the Konqueror web browser will send them to all other web sites operating under the same domain. A malicious website can use this as part of a session fixation attack. See e.g. http://www.acros.si/papers/session_fixation.pdf Affected are all country specific secondary top level domains that use more than 2 characters in the secondary part of the domain name and that use a secondary part other than com, net, mil, org, gov, edu or int. Examples of affected domains are .ltd.uk, .plc.uk and .firm.in It should be noted that popular domains such as .co.uk, .co.in and .com are NOT affected. Embargoed until Aug 20
This issue should also affect RHEL2.1 In order to verify this issue, we're going to have to jump through some pretty big hoops.
it's fixed in kdelibs-3.1.3-6.6/kdebase-3.1.3-5.4 for RHEL3 for 2.1AS it still needs doing backport.
public, removing embargo.
