-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : sudo SUMMARY : Buffer overflow vulnerability DATE : 2002-04-26 12:01:00 ID : CLA-2002:475 RELEVANT RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION "sudo"[1] is an utility designed to be used by administrators who wish to delegate administrative privileges to regular users for very specific commands, and without giving away the root password. Global InterSec published[3] an advisory about a memory heap corruption vulnerability[2] in sudo. This vulnerability could possibly be used by local attackers to obtain root privileges. Sudo allows users to specify the password prompt they receive. This prompt can contain macros (such as %h) that will be expanded by sudo. Sudo can be tricked into allocating the wrong ammount of memory for this prompt. SOLUTION It is recommended that all sudo users upgrade their packages.
