                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           netscape
Date:                   July 31st, 2000
Advisory ID:            MDKSA-2000:027

Affected versions:      6.0, 6.1, 7.0, 7.1
________________________________________________________________________

Problem Description:

 Previous versions of Netscape, from version 3.0 to 4.73 contain a
 serious overflow flaw due to improper input verification in Netscape's
 JPEG processing code.  The way Netscape processed JPEG comments trusted
 the length parameter for comment fields.  By manipulating this value,
 it was possible to cause Netscape to read in an excessive amount of
 data which would then overwrite memory.  Data with a malicious design
 could allow a remote site to execute arbitrary code as the user of
 Netscape on the client system.  It is highly recommended that everyone 
 using Netscape upgrade to this latest version that fixes the flaw.
________________________________________________________________________

Please verify these md5 checksums of the updates prior to upgrading to
ensure the integrity of the downloaded package.  You can do this by
running the md5sum program on the downloaded package by using
"md5sum package.rpm".

To upgrade automatically, use « MandrakeUpdate ».  

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

You can download the updates directly from:
   ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates
   ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors 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 7.1, look for it in "updates/7.1/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, so if you want an immediate upgrade, please use one of the two 
above-listed mirrors.
