                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:		exmh
Date:			January 26th, 2001
Advisory ID:		MDKSA-2001:015

Affected versions:	6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

 All versions of exmh prior to 2.3.1 use the /tmp directory for storing
 temporary files.  This was done in an insecure manner as exmh did not
 check to ensure that nobody placed a symlink with the same name in /tmp
 in the meantime and thus was vulnerable to a symlink attack.  This
 could lead to a malicious local user being able to overwrite any file
 writable by the user executing exmh.  These updated versions of exmh
 now use /tmp/username unless TMPDIR or EXMHTMPDIR is set.
________________________________________________________________________

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
  http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.

To upgrade automatically, use MandrakeUpdate.  

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

You can download the updates directly from one of the mirror sites
listed at:

  http://www.linux-mandrake.com/en/ftp.php3.  

Updated packages are available in the "updates/[ver]/RPMS/" directory. 
 
For example, if you are looking for an updated RPM package for
Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/".  Updated source
RPMs are available as well, but you generally do not need to download
them.

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