Mandrake Linux Security Advisory : kdelibs (MDKSA-2005:058)
High Nessus Plugin ID 17346
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionA vulnerability in dcopserver was discovered by Sebastian Krahmer of the SUSE security team. A local user can lock up the dcopserver of other users on the same machine by stalling the DCOP authentication process, causing a local Denial of Service. dcopserver is the KDE Desktop Communication Procotol daemon (CVE-2005-0396).
As well, the IDN (International Domain Names) support in Konqueror is vulnerable to a phishing technique known as a Homograph attack. This attack is made possible due to IDN allowing a website to use a wide range of international characters that have a strong resemblance to other characters. This can be used to trick users into thinking they are on a different trusted site when they are in fact on a site mocked up to look legitimate using these other characters, known as homographs. This can be used to trick users into providing personal information to a site they think is trusted (CVE-2005-0237).
Finally, it was found that the dcopidlng script was vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files of a user when the script is run on behalf of that user. However, this script is only used as part of the build process of KDE itself and may also be used by the build processes of third- party KDE applications (CVE-2005-0365).
The updated packages are patched to deal with these issues and Mandrakesoft encourages all users to upgrade immediately.
SolutionUpdate the affected packages.
