Package:             spamassassin
Vulnerability:       denial of service
OpenPKG Specific:    no

Affected Releases:   Affected Packages:         Corrected Packages:
OpenPKG CURRENT      N.A.                       N.A.
OpenPKG 2.1          N.A.                       N.A.
OpenPKG 2.0          <= spamassassin-2.63-2.0.0 >= spamassassin-2.63-2.0.1

Dependent Packages:  none

Description:
  According to a vendor announcement [1], a Denial of Service (DoS)
  vulnerability exists in the email spam filter SpamAssassin [0]
  versions 2.5x and 2.6x. The problem can be exploited by sending
  certain malformed Email messages. The Common Vulnerabilities and
  Exposures (CVE) project assigned the id CAN-2004-0796 [2] to the
  problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  rpm -q spamassassin". If you have the "spamassassin" package installed
  and its version is affected (see above), we recommend that you
  immediately upgrade it (see Solution) [3][4].

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [5], fetch it from the OpenPKG FTP service [6] or a mirror location,
  verify its integrity [7], build a corresponding binary RPM from it [3]
  and update your OpenPKG installation by applying the binary RPM [4].
  For the affected release OpenPKG 2.0, perform the following operations
  to permanently fix the security problem (for other releases adjust
  accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.0/UPD
  ftp> get spamassassin-2.63-2.0.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig spamassassin-2.63-2.0.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild spamassassin-2.63-2.0.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/spamassassin-2.63-2.0.1.*.rpm
