Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200408-23
(kdelibs: Cross-domain cookie injection vulnerability)

kcookiejar contains a vulnerability which may allow a malicious website to
set cookies for other websites under the same second-level domain.
This vulnerability applies to 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. However, certain popular domains, such as co.uk, are not affected.

Impact :

Users visiting a malicious website using the Konqueror browser may have a
session cookie set for them by that site. Later, when the user visits
another website under the same domain, the attacker's session cookie will
be used instead of the cookie issued by the legitimate site. Depending on
the design of the legitimate site, this may allow an attacker to gain
access to the user's session. For further explanation on this type of
attack, see the paper titled 'Session Fixation Vulnerability in
Web-based Applications' (reference 2).

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of kdelibs.
