-----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-2003.028 07-Apr-2003 ________________________________________________________________________ Package: samba Vulnerability: remote root exploit OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= samba-2.2.8-20030405 >= samba-2.2.8a-20030407 OpenPKG 1.2 <= samba-2.2.7a-1.2.1 >= samba-2.2.7a-1.2.2 OpenPKG 1.1 <= samba-2.2.5-1.1.2 >= samba-2.2.5-1.1.3 Dependent Packages: none Description: Digital Defense Inc. has discovered [1] a buffer overflow vulnerability in the Samba SMB/CIFS server [0]. An intruder exploiting this vulnerability could gain root access on the affected host system. An active exploit is publically available [2]. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0201 [3] to the problem. Additional buffer overflows were detected by an internal code audit by the Samba team in response to the original report. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0196 [4] to these additional problems. 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). [5][6] Solution: Select the updated source RPM appropriate for your OpenPKG release [7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror location, verify its integrity [11], build a corresponding binary RPM from it [5] and update your OpenPKG installation by applying the binary RPM [6]. 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-1.2.2.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig samba-2.2.7a-1.2.2.src.rpm $ <prefix>/bin/rpm --rebuild samba-2.2.7a-1.2.2.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/samba-2.2.7a-1.2.2.*.rpm ________________________________________________________________________ References: [0] http://www.samba.org/ [1] http://www.digitaldefense.net/labs/advisories/DDI-1013.txt [2] http://www.digitaldefense.net/labs/tools/trans2root.pl [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0201 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0196 [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/samba-2.2.5-1.1.3.src.rpm [8] ftp://ftp.openpkg.org/release/1.2/UPD/samba-2.2.7a-1.2.2.src.rpm [9] ftp://ftp.openpkg.org/release/1.1/UPD/ [10] ftp://ftp.openpkg.org/release/1.2/UPD/ [11] 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 retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
