-----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-2003.006 23-Jan-2003 ________________________________________________________________________ Package: python Vulnerability: predictable filename allows arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= python-2.2.1-20020820 >= python-2.2.2-20021015 OpenPKG 1.2 none N.A. OpenPKG 1.1 <= python-2.2.1-1.1.0 >= python-2.2.1-1.1.1 Affected Releases: Dependent Packages: none Description: Zack Weinberg discovered an insecure use of a predictable file name [0] in the Python programming language [1]. Python attempts to execute a file which is assumed to not exist just to find out what error the operating system returns in this situation. It uses a constant filename for this task which could lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2002-1119 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q python". If you have the "python" 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 release OpenPKG 1.1, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.1/UPD ftp> get python-2.2.1-1.1.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig python-2.2.1-1.1.1.src.rpm $ <prefix>/bin/rpm --rebuild python-2.2.1-1.1.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/python-2.2.1-1.1.1.*.rpm ________________________________________________________________________ References: [0] http://mail.python.org/pipermail/python-dev/2002-August/027223.html [1] http://www.python.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1119 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.1/UPD/python-2.2.1-1.1.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.1/UPD/ [7] 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 find under the official URL http://www.openpkg.org/openpkg.pgp or on http://keyserver.pgp.com/.
