-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org email@example.com firstname.lastname@example.org OpenPKG-SA-2004.040 15-Sep-2004 ________________________________________________________________________ Package: samba Vulnerability: denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= samba-3.0.6-20040820 >= samba-3.0.7-20040913 OpenPKG 2.1 <= samba-3.0.4-2.1.1 >= samba-3.0.4-2.1.2 OpenPKG 2.0 N.A. N.A. Dependent Packages: none Description: According to a security advisory  from the Samba team and two corresponding security advisories  from iDEFENSE, two Denial of Service (DoS) vulnerabilities exists in the Samba SMB/CIFS server . The first DoS bug is in smbd(8) and may allow an unauthenticated user to cause smbd(8) to spawn new processes, each one entering an infinite loop. After sending a sufficient amount of packets it is possible to exhaust the memory resources on the server. The second DoS bug in nmbd(8) may allow an attacker to remotely crash the nmbd(8) daemon. The Common Vulnerabilities and Exposures (CVE) project assigned the ids CAN-2004-0807  and CAN-2004-0808  to the problems. Please check whether you are affected by running "
/bin/openpkg 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) . Solution: Select the updated source RPM appropriate for your OpenPKG release , fetch it from the OpenPKG FTP service  or a mirror location, verify its integrity , build a corresponding binary RPM from it  and update your OpenPKG installation by applying the binary RPM . For the most recent release OpenPKG 2.1, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.1/UPD ftp> get samba-3.0.4-2.1.2.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig samba-3.0.4-2.1.2.src.rpm $ /bin/openpkg rpm --rebuild samba-3.0.4-2.1.2.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/samba-3.0.4-2.1.2.*.rpm ________________________________________________________________________ References:  http://www.samba.org/  http://us3.samba.org/samba/history/3.0_DOS_sept04_announce.txt  http://www.idefense.com/application/poi/display?id=138  http://www.idefense.com/application/poi/display?id=139  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0807  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0808  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/2.1/UPD/samba-3.0.4-2.1.2.src.rpm  ftp://ftp.openpkg.org/release/2.1/UPD/  http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG "(ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
