Description:
According to a vendor announcement [1], a vulnerability exists in
the Apache HTTP server [0], version 1.3. The problem is a potential
buffer overflow in the "get_tag" function of Apache's SSI module
"mod_include". It allows local users who can create SSI documents
to execute arbitrary code as the Apache run-time user via SSI
documents that trigger a content length calculation error. The
Common Vulnerabilities and Exposures (CVE) project assigned the id
CAN-2004-0940 [2] to the problem.
Please check whether you are affected by running "<prefix>/bin/openpkg
rpm -q apache". If you have the "apache" 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 most recent release OpenPKG 2.2, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.2/UPD
ftp> get apache-1.3.31-2.2.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig apache-1.3.31-2.2.1.src.rpm
