-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org email@example.com firstname.lastname@example.org OpenPKG-SA-2004.018 30-Apr-2004 ________________________________________________________________________ Package: proftpd Vulnerability: privilege escalation OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= proftpd-1.2.9-20040207 >= proftpd-1.2.10rc1-20040429 OpenPKG 2.0 <= proftpd-1.2.9-2.0.0 >= proftpd-1.2.9-2.0.1 OpenPKG 1.3 N.A. none Dependent Packages: none Description: A portability workaround was applied in version 1.2.9 of the FTP server ProFTPD . As a side-effect, CIDR based (aaa.bbb.ccc.ddd/NN) ACL entries in "Allow" and "Deny" directives act like an "AllowAll" directive and so FTP clients are granted access to files and directories although the server configuration might explicitly deny this . Please check whether you are affected by running "
/bin/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) . Solution: Select the updated source RPM appropriate for your OpenPKG release , fetch it from the OpenPKG FTP service  or a mirror location, verify its integrity , build a corresponding binary RPM from it  and update your OpenPKG installation by applying the binary RPM . For the most recent release OpenPKG 2.0, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.0/UPD ftp> get proftpd-1.2.9-2.0.1.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig proftpd-1.2.9-2.0.1.src.rpm $ /bin/openpkg rpm --rebuild proftpd-1.2.9-2.0.1.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/proftpd-1.2.9-2.0.1.*.rpm ________________________________________________________________________ References:  http://www.proftpd.org/  http://bugs.proftpd.org/show_bug.cgi?id=2267  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/2.0/UPD/proftpd-1.2.9-2.0.1.src.rpm  ftp://ftp.openpkg.org/release/2.0/UPD/  http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG "(ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
