The starting offsets for the loops are calculated incorrectly which may cause a buffer overrun beyond the beginning of the row buffer. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2002-1363 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -qa 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 it's 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 current release OpenPKG 1.1, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.1/UPD ftp> get png-1.2.4-1.1.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig png-1.2.4-1.1.1.src.rpm $ <prefix>/bin/rpm --rebuild png-1.2.4-1.1.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/png-1.2.4-1.1.1.*.rpm Additionally, we recommend that you rebuild and reinstall all dependent packages (see above), if any, too.
