OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [EMAIL PROTECTED] [EMAIL PROTECTED] OpenPKG-SA-2004.015 16-Apr-2004 ________________________________________________________________________ Package: ethereal Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= ethereal-0.10.2-20040329 >= ethereal-0.10.3-20040330 OpenPKG 2.0 <= ethereal-0.10.0a-2.0.0 >= ethereal-0.10.0a-2.0.1 OpenPKG 1.3 <= ethereal-0.9.14-1.3.0 >= ethereal-0.9.14-1.3.1 Dependent Packages: none Description: According to a vendor security advisory [0] based on hints from Stefan Esser and Jonathan Heussser, several vulnerabilities of various types exist in the Ethereal network protocol analyzer [1]. Namely, it may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully malformed packet onto the wire, by convincing someone to read a malformed packet trace file, or by creating a malformed color filter file. The Common Vulnerabilities and Exposures (CVE) project assigned the identifiers CAN-2004-0176 [2] and CAN-2004-0365 [3] to the problems concerning protocol dissectors and RADIUS packets. The zero-length presentation protocol selector vulnerability named in the Ethereal vendor advisory does not affect OpenPKG though, because such presentation protocol selectors are not implemented in any Ethereal versions released by OpenPKG. Please check whether you are affected by running "<prefix>/bin/rpm -q ethereal". If you have the "ethereal" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) [4][5]. Solution: Select the updated source RPM appropriate for your OpenPKG release [6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror location, verify its integrity [10], build a corresponding binary RPM from it [4] and update your OpenPKG installation by applying the binary RPM [5]. 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 ethereal-0.10.0a-2.0.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig ethereal-0.10.0a-2.0.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild ethereal-0.10.0a-2.0.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/ethereal-0.10.0a-2.0.1.*.rpm ________________________________________________________________________ References: [0] http://www.ethereal.com/appnotes/enpa-sa-00013.html [1] http://www.ethereal.com/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0176 [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0365 [4] http://www.openpkg.org/tutorial.html#regular-source [5] http://www.openpkg.org/tutorial.html#regular-binary [6] ftp://ftp.openpkg.org/release/1.3/UPD/ethereal-0.9.14-1.3.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.0/UPD/ethereal-0.10.0a-2.0.1.src.rpm [8] ftp://ftp.openpkg.org/release/1.3/UPD/ [9] ftp://ftp.openpkg.org/release/2.0/UPD/ [10] 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 retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
