Description:
Tavis Ormandy from Gentoo discovered a Denial of Service (DoS)
vulnerability in the ZLib compression library [1] versions 1.2.x
(older versions are not affected). An error in the handling of corrupt
compressed data streams can result in a buffer being overflowed. By
carefully crafting a corrupt compressed data stream, an attacker
could overwrite data structures in a ZLib-using application. The
Common Vulnerabilities and Exposures (CVE) project assigned the id
CAN-2005-2096 [2] to the problem.
Please check whether you are affected by running "<prefix>/bin/openpkg
rpm -q zlib". If you have the "zlib" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution) and its dependent packages (see above), too [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 2.4, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.4/UPD
ftp> get zlib-1.2.2-2.4.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig zlib-1.2.2-2.4.1.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild zlib-1.2.2-2.4.1.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/zlib-1.2.2-2.4.1.*.rpm
Additionally, we recommend that you rebuild and reinstall
all dependent packages (see above), if any, too [3][4].
