-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-securityat_private openpkgat_private OpenPKG-SA-2003.009 18-Feb-2003 ________________________________________________________________________ Package: w3m Vulnerability: cookie information leak OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= w3m-0.3.2.1-20021126 >= w3m-0.3.2.2-20021205 OpenPKG 1.2 N.A. >= w3m-0.3.2.2-1.2.0 OpenPKG 1.1 <= w3m-0.3.1-1.1.0 >= w3m-0.3.1-1.1.1 Affected Releases: Dependent Packages: none Description: According to Hironori Sakamoto, one of the w3m developers, two security vulnerabilities exist in w3m [0]. Releases before 0.3.2.1 do not escape an HTML tag in a frame, which allows remote attackers to access files or cookies [1]. Releases before 0.3.2.2 do not properly escape HTML tags in the ALT attribute of an IMG tag, which could allow remote attackers to access files or cookies [2]. The Common Vulnerabilities and Exposures (CVE) project assigned the ids CAN-2002-1335 [3] and CAN-2002-1348 [4] to these problems. We have backported the patch to the 0.3.1 release. Please check whether you are affected by running "<prefix>/bin/rpm -q w3m". If you have the "w3m" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) [5][6]. Solution: Select the updated source RPM appropriate for your OpenPKG release [7], fetch it from the OpenPKG FTP service [8] or a mirror location, verify its integrity [9], build a corresponding binary RPM from it [5] and update your OpenPKG installation by applying the binary RPM [6]. 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 w3m-0.3.1-1.1.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig w3m-0.3.1-1.1.1.src.rpm $ <prefix>/bin/rpm --rebuild w3m-0.3.1-1.1.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/w3m-0.3.1-1.1.1.*.rpm ________________________________________________________________________ References: [0] http://w3m.sourceforge.net/ [1] http://mi.med.tohoku.ac.jp/~satodai/w3m-dev-en/200211.month/838.html [2] http://mi.med.tohoku.ac.jp/~satodai/w3m-dev-en/200212.month/843.html [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1335 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1348 [5] http://www.openpkg.org/tutorial.html#regular-source [6] http://www.openpkg.org/tutorial.html#regular-binary [7] ftp://ftp.openpkg.org/release/1.1/UPD/w3m-0.3.1-1.1.1.src.rpm [8] ftp://ftp.openpkg.org/release/1.1/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkgat_private>" (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/.
