-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@openpkg.org openpkg@openpkg.org OpenPKG-SA-2004.009 05-Apr-2004 ________________________________________________________________________ Package: mc Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= mc-4.6.0-20040207 >= mc-4.6.0-20040405 OpenPKG 2.0 <= mc-4.6.0-2.0.0 >= mc-4.6.0-2.0.1 OpenPKG 1.3 <= mc-4.6.0-1.3.0 >= mc-4.6.0-1.3.1 Dependent Packages: none Description: According to a message from Ilya Teterin posted on Bugtraq [0], the Midnight Commander application [1] uses a uninitialized buffer to handle symlinks in VFS. This allows attackers to execute arbitrary code during symlink conversion. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-1023 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q mc". If you have the "mc" 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 2.0, 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 mc-4.6.0-2.0.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig mc-4.6.0-2.0.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild mc-4.6.0-2.0.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/mc-4.6.0-2.0.1.*.rpm ________________________________________________________________________ References: [0] http://marc.theaimsgroup.com/?l=bugtraq&m=106399528518704 [1] http://www.ibiblio.org/mc/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-1023 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.3/UPD/mc-4.6.0-1.3.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.0/UPD/mc-4.6.0-2.0.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.3/UPD/ [8] ftp://ftp.openpkg.org/release/2.0/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@openpkg.org>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
