[GLSA-200405-11] KDE URI Handler Vulnerabilities

Vulnerability Assessment Summary
KDE URI Handler Vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200405-11
(KDE URI Handler Vulnerabilities)

The telnet, rlogin, ssh and mailto URI handlers in KDE do not check for '-'
at the beginning of the hostname passed. By crafting a malicious URI and
entice an user to click on it, it is possible to pass an option to the
programs started by the handlers (typically telnet, kmail...).

Impact

If the attacker controls the options passed to the URI handling programs,
it becomes possible for example to overwrite arbitrary files (possibly
leading to denial of service), to open kmail on a possible hacker-controlled
remote display or with an alternate configuration file (possibly leading to
control of the user account).

Workaround

There is no known workaround at this time. All users are advised to upgrade
to a corrected version of kdelibs.

Solution:
Users of KDE 3.1 should upgrade to the corrected version of kdelibs:
# emerge sync
# emerge -pv "=kde-base/kdelibs-3.1.5-r1"
# emerge "=kde-base/kdelibs-3.1.5-r1"
Users of KDE 3.2 should upgrade to the latest available version of kdelibs:
# emerge sync
# emerge -pv ">=kde-base/kdelibs-3.2.2-r1"
# emerge ">=kde-base/kdelibs-3.2.2-r1"

Network Security Threat Level: Medium
