Package: apache (option "with_mod_ssl yes" only)
Vulnerability: information disclosure
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= apache-1.3.31-20041005>= apache-1.3.31-20041015
OpenPKG 2.1 <= apache-1.3.31-2.1.4>= apache-1.3.31-2.1.5
OpenPKG 2.0 <= apache-1.3.29-2.0.5>= apache-1.3.29-2.0.6
Dependent Packages: none
Description:
Hartmut Keil discovered [0] an information disclosure vulnerability
in mod_ssl [1], the SSL/TLS module of the Apache [2] webserver. After
a renegotiation, affected versions of mod_ssl fail to ensure that the
requested cipher suite is actually negotiated. In some configurations
a client may be able to retrieve content using a cipher suite the
server does not consider strong enough. The Common Vulnerabilities
and Exposures (CVE) project assigned the id CAN-2004-0885 [3] to the
problem.
Please check whether you are affected by running "/bin/rpm -q
apache" and "/bin/rpm -qi apache | grep with_mod_ssl". If you
have the "apache" package with option "with_mod_ssl" installed and its
version is affected (see above), we recommend that you immediately
upgrade (see Solution) [4][5].
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
location, verify its integrity [10], build a corresponding binary RPM
from it [4] and update your OpenPKG installation by applying the binary
RPM [5]. For the current release OpenPKG 2.1, perform the following
operations to permanently fix the security problem (for other releases
adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.1/UPD
ftp> get apache-1.3.31-2.1.5.src.rpm
ftp> bye
$ /bin/rpm -v --checksig apache-1.3.31-2.1.5.src.rpm
$ /bin/rpm --rebuild apache-1.3.31-2.1.5.src.rpm
$ su -
# /bin/rpm -Fvh /RPM/PKG/apache-1.3.31-2.1.5.*.rpm
