-----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-2004.009 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 , the Midnight Commander application  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  to the problem. Please check whether you are affected by running "
/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).  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 mc-4.6.0-2.0.1.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig mc-4.6.0-2.0.1.src.rpm $ /bin/openpkg rpm --rebuild mc-4.6.0-2.0.1.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/mc-4.6.0-2.0.1.*.rpm ________________________________________________________________________ References:  http://marc.theaimsgroup.com/?l=bugtraq&m=106399528518704  http://www.ibiblio.org/mc/  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-1023  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/1.3/UPD/mc-4.6.0-1.3.1.src.rpm  ftp://ftp.openpkg.org/release/2.0/UPD/mc-4.6.0-2.0.1.src.rpm  ftp://ftp.openpkg.org/release/1.3/UPD/  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.
