Package: apache
Vulnerability: denial of service
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= apache-1.3.31-20040608 >= apache-1.3.31-20040611

Description:
According to a security advisory from Georgi Guninski [0] there
is a buffer overflow in Apache's [1] mod_proxy module. The Common
Vulnerabilities and Exposures (CVE) project assigned the id
CAN-2004-0492 [2] to the problem.
Please check whether you are affected by running "/bin/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 2.0, 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 apache-1.3.29-2.0.3.src.rpm
ftp> bye
$ /bin/openpkg rpm -v --checksig apache-1.3.29-2.0.3.src.rpm
$ /bin/openpkg rpm --rebuild apache-1.3.29-2.0.3.src.rpm
$ su -
# /bin/openpkg rpm -Fvh /RPM/PKG/apache-1.3.29-2.0.3.*.rpm
