RHSA-2002-221: arts Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the arts packages

Detailed Explanation for this Vulnerability Test

A number of vulnerabilities have been found that affect various versions of
KDE. This errata provides updates for these issues.

KDE is a graphical desktop environment for workstations. A number
of vulnerabilities have been found in various versions of KDE.

The SSL capability for Konqueror in KDE 3.0.2 and earlier does not
verify the Basic Constraints for an intermediate CA-signed certificate,
which allows remote attackers to spoof the certificates of trusted
sites via a man-in-the-middle attack. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2002-0970 to this issue.

The cross-site scripting protection for Konqueror in KDE 2.2.2 and 3.0
through 3.0.3 does not properly initialize the domains on sub-frames
and sub-iframes, which can allow remote attackers to execute scripts
and steal cookies from subframes that are in other domains. (CVE-2002-1151)

Multiple buffer overflows exist in the KDE LAN browsing implementation

the reslisa daemon contains a buffer overflow vulnerability which could
be exploited if the reslisa binary is SUID root. Additionally, the lisa
daemon contains a vulnerability which potentially enables any local
user, as well any any remote attacker on the LAN who is able to gain
control of the LISa port (7741 by default), to obtain root rights.
In Red Hat Linux reslisa is not SUID root and lisa services are not
automatically started. (CVE-2002-1247, CVE-2002-1306)

Red Hat Linux Advanced Server 2.1 provides KDE version 2.2.2 and is
therefore vulnerable to these issues. This errata provides new kdelibs and
kdenetworks packages which contain patches to correct these issues.

Please note that there is are two additional vulnerabilities that affect
KDE 2.x which are not fixed by this errata. A vulnerability in the rlogin
KIO subsystem (rlogin.protocol) of KDE 2.x 2.1 and later, and KDE 3.x 3.0.4
and earlier, allows local and remote attackers to execute arbitrary code
via a carefully crafted URL. (CVE-2002-1281). A similar vulnerability
affects the telnet KIO subsystem (telnet.protocol) of KDE 2.x 2.1 and
later. (CVE-2002-1282)

At this time, Red Hat recommends disabling both the rlogin and telnet
KIO protocols as a workaround. To disable both protocols, execute
these commands while logged in as root:

rm /usr/share/services/rlogin.protocol
rm /usr/share/services/telnet.protocol

Threat Level: High
