-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@xxxxxxxxxxx openpkg@xxxxxxxxxxx OpenPKG-SA-2005.020 06-Sep-2005 ________________________________________________________________________ Package: proftpd Vulnerability: denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= proftpd-1.3.0rc1-20050610 >= proftpd-1.3.0rc2-20050725 OpenPKG 2.4 <= proftpd-1.3.0rc1-2.4.0 >= proftpd-1.3.0rc1-2.4.1 OpenPKG 2.3 <= proftpd-1.2.10-2.3.1 >= proftpd-1.2.10-2.3.2 Dependent Packages: none Description: It was reported that ProFTPd [1] version before 1.3.0rc2 suffer from two format string vulnerabilities. In the first, a user with the ability to create a directory could trigger the format string error if there is a ProFTPd shutdown message configured to use the "%C", "%R", or "%U" variables. In the second, the error is triggered if the ProFTPd extension mod_sql is used to retrieve messages from a database and if format strings have been inserted into the database by a user with permission to do so. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2390 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q proftpd". If you have the "proftpd" 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][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 2.4, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.4/UPD ftp> get proftpd-1.3.0rc1-2.4.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig proftpd-1.3.0rc1-2.4.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild proftpd-1.3.0rc1-2.4.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/proftpd-1.3.0rc1-2.4.1.*.rpm ________________________________________________________________________ References: [1] http://www.proftpd.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2390 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.4/UPD/proftpd-1.3.0rc1-2.4.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.3/UPD/proftpd-1.2.10-2.3.2.src.rpm [7] ftp://ftp.openpkg.org/release/2.4/UPD/ [8] ftp://ftp.openpkg.org/release/2.3/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.
