Directory traversal vulnerability in KGet in KDE SC 4.0.0 through 4.4.3 allows remote attackers to create arbitrary files via directory traversal sequences in the name attribute of a file element in a metalink file.

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.

Race condition in workspace/krunner/lock/lockdlg.cc in the KRunner lock module in kdebase in KDE SC 4.4.0 allows physically proximate attackers to bypass KScreenSaver screen locking and access an unattended workstation by pressing the Enter key at a certain time, related to multiple forked processes.

KDE-Workspace 4.10.5 and earlier does not properly handle the return value of the glibc 2.17 crypt and pwencrypt functions, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via (1) an invalid salt or a (2) DES or (3) MD5 encrypted password, when FIPS-140 is enable, to KDM or an (4) invalid password to KCheckPass.
