-----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-2003.021 18-Mar-2003 ________________________________________________________________________ Package: samba Vulnerability: remote root exploit / chown race condition OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= samba-2.2.7a-20030207 >= samba-2.2.8-20030316 OpenPKG 1.2 <= samba-2.2.7a-1.2.0 >= samba-2.2.7a-1.2.1 OpenPKG 1.1 <= samba-2.2.5-1.1.1 >= samba-2.2.5-1.1.2 Dependent Packages: none Description: Sebastian Krahmer, SuSE Security Team, [0] has alerted the Samba Team to two serious vulnerabilities in all versions of Samba [1] up to and including version 2.2.7a. We have backported the security relevant pieces of the 2.2.8 vendor changes into releases used by OpenPKG. If exploited correctly, it could lead to an anonymous user gaining root access on a Samba serving system. All versions of Samba up to and including Samba 2.2.7a are vulnerable. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0085 [2] to the problem. In addition he pointed out a chown(2) race condition which could allow overwriting of critical system files if exploited. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0086 [3] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q samba". If you have the "samba" 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 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 samba-2.2.7a-1.2.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig samba-2.2.7a-1.2.1.src.rpm $ <prefix>/bin/rpm --rebuild samba-2.2.7a-1.2.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/samba-2.2.7a-1.2.1.*.rpm ________________________________________________________________________ References: [0] http://www.suse.de/de/security/ [1] http://www.samba.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0085 [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0086 [4] http://www.openpkg.org/tutorial.html#regular-source [5] http://www.openpkg.org/tutorial.html#regular-binary [6] ftp://ftp.openpkg.org/release/1.1/UPD/samba-2.2.5-1.1.2.src.rpm [7] ftp://ftp.openpkg.org/release/1.2/UPD/samba-2.2.7a-1.2.1.src.rpm [8] ftp://ftp.openpkg.org/release/1.1/UPD/ [9] ftp://ftp.openpkg.org/release/1.2/UPD/ [10] 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/.
