OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [EMAIL PROTECTED] [EMAIL PROTECTED] OpenPKG-SA-2003.016 04-Mar-2003 ________________________________________________________________________ Package: sendmail Vulnerability: code execution, root exploit OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= sendmail-8.12.7-20030205 >= sendmail-8.12.8-20030304 OpenPKG 1.2 <= sendmail-8.12.7-1.2.0 >= sendmail-8.12.7-1.2.1 OpenPKG 1.1 none N.A. Dependent Packages: none Description: According to an ISS X-Force advisory [1], a buffer overflow vulnerability exists in all versions from 5.79 to 8.12.7 of the Sendmail MTA [0]. Attackers may remotely exploit this vulnerability to gain "root" or superuser control of any vulnerable Sendmail server. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2002-1337 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q sendmail". If you have the "sendmail" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution). [3][4] Solution: Select the updated source RPM appropriate for your OpenPKG release [5], fetch it from the OpenPKG FTP service [6] or a mirror location, verify its integrity [7], build a corresponding binary RPM from it [3] and update your OpenPKG installation by applying the binary RPM [4]. For the current release OpenPKG 1.2, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.2/UPD ftp> get sendmail-8.12.7-1.2.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig sendmail-8.12.7-1.2.1.src.rpm $ <prefix>/bin/rpm --rebuild sendmail-8.12.7-1.2.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/sendmail-8.12.7-1.2.1.*.rpm ________________________________________________________________________ References: [0] http://www.sendmail.org/ [1] http://www.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21950 [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1337 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.2/UPD/sendmail-8.12.7-1.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.2/UPD/ [7] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <[EMAIL PROTECTED]>" (ID 63C4CB9F) of the OpenPKG project which you can find under the official URL http://www.openpkg.org/openpkg.pgp or on http://keyserver.pgp.com/.
