OpenPKG-SA-2002.004 19-Jun-2002

Package: apache
Vulnerability: remote DoS / exploit
OpenPKG Specific: no
Affected Releases: OpenPKG 1.0
Affected Packages: <= apache-1.3.22-1.0.1
Corrected Packages: >= apache-1.3.22-1.0.2
Dependent Packages: -
Description:
According to a Security Bulletin from the Apache Software Foundation
[5] and a corresponding CERT Security Advisory [6], there is a
remotely exploitable vulnerability in the way that the Apache web
server handles data encoded in chunks. This bug can be triggered
remotely by sending a carefully crafted invalid request. This
functionality is enabled by default.
Please check whether you are affected by running "<prefix>/bin/rpm -qa
apache". If you have the "apache" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution).
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[4], fetch it from the OpenPKG FTP service [3] or a mirror
location, verify its integrity [1], build a corresponding binary RPM
from it and update your OpenPKG installation by applying the binary
RPM [2]. For the latest OpenPKG 1.0 release, perform the following
operations to permanently fix the security problem (for other releases
adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.0/UPD
ftp> get apache-1.3.22-1.0.2.src.rpm
ftp> bye
$ <prefix>/bin/rpm --checksig apache-1.3.22-1.0.2.src.rpm
$ <prefix>/bin/rpm --rebuild apache-1.3.22-1.0.2.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/apache-1.3.22-1.0.2.*.rpm
# <prefix>/etc/rc apache stop start
