                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           cvsweb
Date:                   July 14th, 2000
Advisory ID:            MDKSA-2000:019

Affected versions:      7.1
________________________________________________________________________

Problem Description:

 Cvsweb contains a hole that provides attackers who have write access to
 a cvs repository with shell access.  Thus, attackers who have write
 access to a cvs repository but not shell access can obtain a shell.  In
 addition, anyone with write access to a cvs repository that is viewable
 with cvsweb can get access to whatever user the cvsweb cgi script runs
 as (typically nobody or www-data, etc.).  This update closes all of
 these possibly exploited pipe-opens.
________________________________________________________________________

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".

Linux-Mandrake 7.1:
2a435a7edf358f59a93eb5534efcd273  7.1/RPMS/cvsweb-1.80-3mdk.noarch.rpm
24b7d490f63e154c88909c9b214793e0  7.1/SRPMS/cvsweb-1.80-3mdk.src.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.
