Package: apache [with_mod_ssl=yes]
Vulnerability: format string vulnerability
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= apache-1.3.31-20040714 >= apache-1.3.31-20040716
OpenPKG 2.1 <= apache-1.3.31-2.1.0 >= apache-1.3.31-2.1.1
OpenPKG 2.0 <= apache-1.3.29-2.0.3 >= apache-1.3.29-2.0.4
OpenPKG 1.3 <= apache-1.3.28-1.3.5 >= apache-1.3.28-1.3.6
Dependent Packages: none
Description:
Triggered by a report to Packet Storm [1] from Virulent, a format
string vulnerability was found in mod_ssl [2], the Apache SSL/TLS
interface to OpenSSL, version (up to and including) 2.8.18 for Apache
1.3. The mod_ssl in Apache 2.x is not affected. The vulnerability
could be exploitable if Apache is used as a proxy for HTTPS URLs and
the attacker established a own specially prepared DNS and origin
server environment.
Please check whether you are affected by running "<prefix>/bin/rpm -q
apache" and "<prefix>/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) [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-1.3.29-2.0.4.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig apache-1.3.29-2.0.4.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild --with mod_ssl
apache-1.3.29-2.0.4.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/apache-1.3.29-2.0.4.*.rpm
