Description Jarno Huuskonen 2000-10-11 09:28:28 UTC 
Hi,

Sudo doesn't clean LANG / LC_xxx environment. So users can use
something like LANG=../../../tmp and if they can run a program with
higher privileges --> possible to exploit. To fix this sudo should clean
LANG / LC_xxx if they contain '/' (like the new userhelper does).

-Jarno

PS. Users can exploit this only if they can run the programs with sudo and
the program has i18n support.

Hm, am I wrong or would this justify a security errata update instead of just 
rawhide?

Changing severity to "security".
