Unknown vulnerability in the telnet KIO subsystem (telnet.protocol) of KDE 2.x 2.1 and later allows local and remote attackers to execute arbitrary code via a certain URL.
Multiple buffer overflows in LISa on KDE 2.x for 2.1 and later, and KDE 3.x before 3.0.4, allow (1) local and possibly remote attackers to execute arbitrary code via the "lisa" daemon, and (2) remote attackers to execute arbitrary code via a certain "lan://" URL.
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.
Konqueror in KDE 3.0 through 3.0.2 does not properly detect the "secure" flag in an HTTP cookie, which could cause Konqueror to send the cookie across an unencrypted channel, which could allow remote attackers to steal the cookie via sniffing.
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.
