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 script and steal cookies from subframes that are in other domains.

A cross site scripting problem has been discovered in Konqueror, a famous browser for KDE and other programs using KHTML. The KDE team reportsthat Konqueror's cross site scripting protection fails to initialize the domains on sub-(i)frames correctly. As a result, JavaScript is able to access any foreign subframe which is defined in the HTML source. Users of Konqueror and other KDE software that uses the KHTML rendering engine may become victim of a cookie stealing and other cross site scripting attacks.

The remote host is using KDE Konqueror as a web client. There is a bug in the version used which may allow a rogue web server to execute JavaScript code in the context of a trusted domain. 

A vulnerability was discovered in Konqueror's cross site scripting protection, in that it fails to initialize the domains on sub-(i)frames correctly. Because of this, JavaScript may access any foreign subframe which is defined in the HTML source, which can be used to steal cookies from the client and allow other cross-site scripting attacks. This also affects other KDE software that uses the KHTML rendering engine.

This is fixed in KDE 3.0.3a, and the KDE team provided a patch for KDE 2.2.2. This patch has been applied to the following packages.

After upgrading kdelibs, you must restart KDE in order for the fix to work.

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 privileges. 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
