                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           licq
Date:                   March 23rd, 2001
Original Advisory Date: March 20th, 2001
Advisory ID:            MDKSA-2001:032-1

Affected versions:      7.1, 7.2, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

 Versions of Licq prior to 1.0.3 have a vulnerability involving the way
 Licq parses received URLs.  The received URLs are passed to the web
 browser without any sanity checking by using the system() function.
 Because of the lack of checks on the URL, remote attackers can pipe
 other commands with the sent URLs causing the client to unwillingly
 execute arbitrary commands.  The URL parsing code has been fixed in
 the most recent 1.0.3 version.

 Users of Linux-Mandrake 7.1 and Corporate Server 1.0.1 will have to
 manually remove the licq-data package by using "rpm -e licq-data"
 prior
 to upgrading.

Update:

 The Licq update for Linux-Mandrake 7.2 was built against the qt2
 libraries available in MandrakeFreq.  As such, the previously released
 Licq packages will be made available in MandrakeFreq and users of
 Linux-Mandrake 7.2 without MandrakeFreq or the "unsupported" updates
 applied should use these new packages. 
________________________________________________________________________

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.
