Updated:  Apr 21 2011
Original Entry Date:  May 13 2010
Impact:   Modification of user information

Description:   Two vulnerabilities were reported in KDE KGet. A remote user can cause files to be downloaded to arbitrary directories on the target system. A remote user can cause certain files to be overwritten on the target system.

A remote user can supply a specially crafted 'name' attribute of the 'file' element of a metalink file. When the metalink file is downloaded, the file will be stored in a directory on the target system that is located outside of the download directory [CVE-2010-1000].

When KGet displays a dialog box to allow the user to choose certain metalink file options, the file will be downloaded after a period of time without user input. The file will overwrite any existing file of the same name [CVE-2010-1511].

Stefan Cornelius of Secunia Research reported these vulnerabilities.

Impact:   A remote user can cause files to be downloaded to arbitrary directories on the target system.

A remote user can cause certain files to be overwritten on the target system.
