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.
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.
