Description:
Steve Grubb discovered that the Portable Network Graphics (PNG)
library libpng [1] accesses memory that is out of bounds when creating
an error message. Depending on machine architecture, bounds checking
and other protective measures, this problem could cause the program
to crash if a defective or intentionally prepared PNG image file is
handled by libpng. This can even lead to a Denial of Service (DoS)
situation. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2004-0421 [2] to the problem.

Please check whether you are affected by running "<prefix>/bin/rpm
-q png" (and similarly for the other affected packages which have
PNG included). If you have the "png" package (or one of the others)
installed and its version is affected (see above), we recommend that
you immediately upgrade it (see Solution) and its dependent packages
(see above), if any, 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 2.0, 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 png-1.2.5-2.0.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig png-1.2.5-2.0.1.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild png-1.2.5-2.0.1.src.rpm
$ su -

<prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/png-1.2.5-2.0.1.*.rpm

Additionally, we recommend that you rebuild and reinstall
all dependent packages (see above), if any, too [3][4].
