KDE 2 and KDE 3.1.1 and earlier 3.x versions allows attackers to execute arbitrary commands via (1) PostScript (PS) or (2) PDF files, related to missing -dPARANOIDSAFER and -dSAFER arguments when using the kghostview Ghostscript viewer.

Multiple vulnerabilities in KDE 2 and KDE 3.x through 3.0.5 do not quote certain parameters that are inserted into a shell command, which could allow remote attackers to execute arbitrary commands via (1) URLs, (2) filenames, or (3) e-mail addresses.

Buffer overflow in konqueror in KDE 2.1 through 3.0 and 3.0.2 allows remote attackers to cause a denial of service (crash) via an IMG tag with large width and height attributes.

Buffer overflow in LISa allows local users to gain access to a raw socket via a long LOGNAME environment variable for the resLISa daemon.

Unknown 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 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.

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.

KICQ 2.0.0b1 allows remote attackers to cause a denial of service (crash) via a malformed message.
