KDE2 KDEUtils KLPRFax_Filter Insecure Temporary File Creation Vulnerability

KDE2 KDEUtils KLPRFax_Filter Insecure Temporary File Creation Vulnerability

KDE2 is a freely available, open source X Window System manager. It is maintained by the KDE Project.

klprfax_filter is a program included with KDE2 for fax functionality. A problem exists in the creation of files in the temporary directory. The program does not check for the existance of the klprfax.filter file prior to attempting to send input to it. This makes it possible for a local user to create a symbolic link to any file that is write-accessible by the user executing klprfax_filter, and overwrite the contents of the file.
