Mandrake Linux Security Advisory: sudo, imlib

Apr 26, 2002, 01:20 (0 Talkback[s])

______________________________________________________________________

                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.

To upgrade automatically, use MandrakeUpdate.  The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one 
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".  A list of
FTP mirrors can be obtained from:

  http://www.mandrakesecure.net/en/ftp.php

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:

  rpm --checksig <filename>

All packages are signed by MandrakeSoft for security.  You can obtain
the GPG public key of the Mandrake Linux Security Team from:

  https://www.mandrakesecure.net/RPM-GPG-KEYS

Please be aware that sometimes it takes the mirrors a few hours to 
update.

                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           imlib
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
______________________________________________________________________

Problem Description:

 Previous versions of imlib, prior to 1.9.13, would fall back to the
 NetPBM library which is not suitable for loading untrusted images due
 to various problem in it's code.  The new imlib also fixes some
 problems with arguments passed to malloc().  These problems could allow
 attackers to construct images that could cause crashes or, potentially,
 the execution of arbitrary code when said images are loaded by a viewer
 that uses imlib.  

 Thanks to Alan Cox and Al Viro for discovering the problems.
