Multiple buffer overflows may allow remote attackers to execute arbitrary code via a long FTP URL that is not properly handled by the "xmlNanoFTPScanURL" function, a long proxy URL containing FTP data that is not properly handled by the "xmlNanoFTPScanProxy" function, and other overflows related to the manipulation of DNS length values in "xmlNanoFTPConnect", "xmlNanoHTTPConnectHost", and "xmlNanoHTTPConnectHost". The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0989 [2] to the problems. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q libxml". If you have the "libxml" 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 libxml-2.6.14-2.2.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig libxml-2.6.14-2.2.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild libxml-2.6.14-2.2.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/libxml-2.6.14-2.2.1.*.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/1/379383/2004-10-24/2004-10-30/0 [1] http://xmlsoft.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0989 [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/libxml-2.6.14-2.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.1/UPD/libxml-2.6.11-2.1.1.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.
