Kolab Security Issue 03 20050921
================================

Package:              Kolab Server
Vulnerability:        buffer overflow, DOS, remotely exploitable
Kolab Specific:       no
Dependent Packages:   none


Summary
-------

The Clam AntiVirus package contains a boundary condition error and fails
to handle exceptional conditions, which can be exploited remotely.


Affected Versions
-----------------

This affects all servers which have ClamAV 0.86.2 or earlier versions running.
Kolab Server 2.0.1 and previous releases of the 2.0 branch are affected.


Fixes
-----

Upgrade to ClamAV 0.87.

A new ClamAV RPM is available from the Kolab download mirrors as
security-updates/20050921/clamav-0.87-20050916.src.rpm

A binary RPM for Debian woody (ix86) is available as
security-updates/20050921/clamav-0.87-20050916.ix86-debian3.0-kolab.rpm

The mirrors are listed on http://kolab.org/mirrors.html

While the mirrors are catching up, you can also get the package via rsync:
# rsync -tzv rsync://rsync.kolab.org/kolab/server/security-updates/20050921/clamav-0.87-20050916.src.rpm


This package can be installed on your Kolab Server with

# /kolab/bin/openpkg rpm --rebuild clamav-0.87-20050916.src.rpm
# /kolab/bin/openpkg rpm \
  -Uvh /kolab/RPM/PKG/clamav-0.87-20050916.<ARCH>-<OS>-kolab.rpm

A new /kolab/etc/clamav/clamav.conf will probably be written, remove the
clamav.conf.rpmsave file, run kolabconf and make sure clamav starts:

# rm /kolab/etc/clamav/clamav.conf
# /kolab/sbin/kolabconf
# /kolab/etc/rc clamav start

##optional
# /kolab/bin/freshclam
