We have received reports about two buffer overflows in the
super package which was distributed as part of Debian GNU/Linux. Firstly, for
per-user .supertab files super didn't check for a buffer overflow when creating
the path to the user's .supertab file. Secondly another buffer overflow did
allow ordinary users to overflow super by creating a nasty personal .supertab
file. We recommend you upgrade your super packages immediately.
An analysis of the super vulnerability is available at this
Securityfocus archive page.
