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 "<prefix>/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 $ <prefix>/bin/openpkg rpm -v --checksig png-1.2.5-2.1.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild png-1.2.5-2.1.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/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]. ________________________________________________________________________ References: [1] http://www.libpng.org/pub/png/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0597 [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0598 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0599 [5] http://www.openpkg.org/tutorial.html#regular-source [6] http://www.openpkg.org/tutorial.html#regular-binary [7] ftp://ftp.openpkg.org/release/2.1/UPD/png-1.2.5-2.1.1.src.rpm [8] ftp://ftp.openpkg.org/release/2.0/UPD/png-1.2.5-2.0.3.src.rpm [9] ftp://ftp.openpkg.org/release/2.1/UPD/ [10] ftp://ftp.openpkg.org/release/2.0/UPD/ [11] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
