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 "
/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
$ /bin/openpkg rpm -v --checksig spamassassin-3.0.3-2.4.1.src.rpm
$ /bin/openpkg rpm --rebuild spamassassin-3.0.3-2.4.1.src.rpm
$ su -
# /bin/openpkg rpm -Fvh /RPM/PKG/spamassassin-3.0.3-2.4.1.*.rpm
