There can be an integer overflow when allocating memory in the routine that handles loading of PNG image files. This later leads to heap data structures being overwritten. If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening the image. Similar integer overflow possibilities also exist in other code parts of GD. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0990 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q gd". If you have the "gd" 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 [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 2.2, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.2/UPD ftp> get gd-2.0.28-2.2.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig gd-2.0.28-2.2.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild gd-2.0.28-2.2.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/gd-2.0.28-2.2.1.*.rpm Additionally, we recommend that you rebuild and reinstall all dependent packages (see above), if any, too [3][4]. ________________________________________________________________________ References: [0] http://www.securityfocus.com/archive/1/379382 [1] http://www.boutell.com/gd/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0990 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.2/UPD/gd-2.0.28-2.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.1/UPD/gd-2.0.27-2.1.2.src.rpm [7] ftp://ftp.openpkg.org/release/2.2/UPD/ [8] ftp://ftp.openpkg.org/release/2.1/UPD/ [9] 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.
