SecurityTracker Alert ID:  1012938

CVE Reference:   CVE-2005-0069   (Links to External Site)
Date:  Jan 19 2005
Impact:   Modification of system information, Modification of user information, Root access via local system, User access via local system

Version(s): 6.3
Description:   A vulnerability was reported in vim in the 'tcltags' and 'vimspell.sh' ancillary scripts. A local user may be able to obtain elevated privileges.

Ubuntu reported that the 'tcltags' and 'vimspell.sh' scripts create temporary files in an unsafe manner. A local user can create a symbolic link (symlink) from a critical file on the system to a temporary file to be used by the Vim scripts. Then, when the affected scripts are run by a target user, the symlinked file may be overwritten with the privileges of the target user.

Javier Fernandez-Sanguino Pena is credited with discovering these flaws.

Impact:   A local user may be able to obtain elevated privileges.
Solution:   No solution was available at the time of this entry.
