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.
