rendering/render_replaced.cpp in Konqueror in KDE before 4.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted web page, related to "trying to reuse a frame with a null part."

Directory traversal vulnerability in the KGetMetalink::File::isValidNameAttr function in ui/metalinkcreator/metalinker.cpp in KGet in KDE SC 4.6.2 and earlier allows remote attackers to create arbitrary files via a .. (dot dot) in the name attribute of a file element in a metalink file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1000.

KGet 2.4.2 in KDE SC 4.0.0 through 4.4.3 does not properly request download confirmation from the user, which makes it easier for remote attackers to overwrite arbitrary files via a crafted metalink file.

Race condition in backend/ctrl.c in KDM in KDE Software Compilation (SC) 2.2.0 through 4.4.2 allows local users to change the permissions of arbitrary files, and consequently gain privileges, by blocking the removal of a certain directory that contains a control socket, related to improper interaction with ksm.

The KDE screen saver in KDE before 3.0.5 does not properly check the return value from a certain function call, which allows attackers with physical access to cause a crash and access the desktop session.

KDM in KDE 3.1.3 and earlier does not verify whether the pam_setcred function call succeeds, which may allow attackers to gain root privileges by triggering error conditions within PAM modules, as demonstrated in certain configurations of the MIT pam_krb5 module.

KDM in KDE 3.1.3 and earlier uses a weak session cookie generation algorithm that does not provide 128 bits of entropy, which allows attackers to guess session cookies via brute force methods and gain access to the user session.

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Multiple vulnerabilities in KDE 2 and KDE 3.x through 3.0.5 do not quote certain parameters that are inserted into a shell command, which could allow remote attackers to execute arbitrary commands via (1) URLs, (2) filenames, or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