                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           sudo
Advisory ID:            MDKSA-2002:028
Date:                   April 25th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1
                        Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 A problem was discovered by fc, with further research by Global
 InterSec, in the sudo program with the password prompt parameter
 (-p).  Sudo can be tricked into allocating less memory than it should
 for the prompt and in certain conditions it is possible to exploit this
 flaw to corrupt the heap in such a way that could be used to execute
 arbitary commands.  Because sudo is generally suid root, this can lead
 to an elevation of privilege for local users.
