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

Affected Releases:   Affected Packages:             Corrected Packages:
OpenPKG CURRENT      <= spamassassin-3.0.3-20050603 >= 
spamassassin-3.0.4-20050725
OpenPKG 2.4          <= spamassassin-3.0.3-2.4.0    >= spamassassin-3.0.3-2.4.1
OpenPKG 2.3          <= spamassassin-3.0.2-2.3.0    >= spamassassin-3.0.2-2.3.1


Dependent Packages:  none

Description:
  A Denial of Service (DoS) vulnerability exists in the Email spam
  filter SpamAssassin [1]. The problem can be exploited by sending
  certain malformed Email headers. The Common Vulnerabilities and
  Exposures (CVE) project assigned the id CAN-2005-1266 [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][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
  location, verify its integrity [9], build a corresponding binary
  RPM from it [3] and update your OpenPKG installation by applying
  the binary RPM [4]. For the latest release OpenPKG 2.4, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.4/UPD
  ftp> get spamassassin-3.0.3-2.4.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig spamassassin-3.0.3-2.4.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild spamassassin-3.0.3-2.4.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh 
<prefix>/RPM/PKG/spamassassin-3.0.3-2.4.1.*.rpm
