Description:
During a source code audit, Chris Evans discovered several problems in
the Portable Network Graphics (PNG) library libpng [1], some of which
are security relevant. This OpenPKG update fixes all known issues.
A stack-based buffer overflow in libpng which can be triggered to run
arbitrary code by a malicious png file. The Common Vulnerabilities
and Exposures (CVE) project assigned the id CAN-2004-0597 [2] to the
problem.
A NULL-pointer crash in libpng which can be triggered by a malicious
png file. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2004-0598 [3] to the problem.
Various possible integer overflows in libpng which may have security
consequences. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2004-0599 [4] to the problem.
Please check whether you are affected by running "/bin/openpkg
rpm -q png". If you have the "png" package 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
[5][6].
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror
location, verify its integrity [11], build a corresponding binary
RPM from it [5] and update your OpenPKG installation by applying the
binary RPM [6]. For the most recent 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 png-1.2.5-2.1.1.src.rpm
ftp> bye
$ /bin/openpkg rpm -v --checksig png-1.2.5-2.1.1.src.rpm
$ /bin/openpkg rpm --rebuild png-1.2.5-2.1.1.src.rpm
$ su -
# /bin/openpkg rpm -Fvh /RPM/PKG/png-1.2.5-2.1.1.*.rpm
Additionally, we recommend that you rebuild and reinstall
all dependent packages (see above), if any, too [5][6].
