OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [EMAIL PROTECTED] [EMAIL PROTECTED] OpenPKG-SA-2003.017 04-Mar-2003 ________________________________________________________________________ Package: file Vulnerability: memory allocation problem, stack overflow OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= file-3.40-20030209 >= file-3.41-20030228 OpenPKG 1.2 <= file-3.39-1.2.0 >= file-3.39-1.2.1 OpenPKG 1.1 <= file-3.39-1.1.1 >= file-3.39-1.1.2 Dependent Packages: none N.A. Description: Jeff Johnson found a memory allocation problem and David Endler found a stack overflow corruption problem in the file [1] "Automatic File Content Type Recognition Tool" version 3.41. Nalin Dahyabhai improved ELF section and program header handling in file [1] version 3.40. We believe that file versions without those modifications are vulnerable to memory allocation and stack overflow problems which put security at risk. We have backported the security relevant pieces of the 3.41 and 3.40 vendor changes into OpenPKG releases using vendor version 3.39. Please check whether you are affected by running "<prefix>/bin/rpm -q file". If you have the "file" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution). [2][3] Solution: Select the updated source RPM appropriate for your OpenPKG release [4][5], fetch it from the OpenPKG FTP service [6][7] or a mirror location, verify its integrity [8], build a corresponding binary RPM from it [2] and update your OpenPKG installation by applying the binary RPM [3]. For the current release OpenPKG 1.2, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.2/UPD ftp> get file-3.39-1.2.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig file-3.39-1.2.1.src.rpm $ <prefix>/bin/rpm --rebuild file-3.39-1.2.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/file-3.39-1.2.1.*.rpm ________________________________________________________________________ References: [1] ftp://ftp.astron.com/pub/file/ [2] http://www.openpkg.org/tutorial.html#regular-source [3] http://www.openpkg.org/tutorial.html#regular-binary [4] ftp://ftp.openpkg.org/release/1.1/UPD/file-3.39-1.1.2.src.rpm [5] ftp://ftp.openpkg.org/release/1.2/UPD/file-3.39-1.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.1/UPD/ [7] ftp://ftp.openpkg.org/release/1.2/UPD/ [8] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <[EMAIL PROTECTED]>" (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/.
