-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@xxxxxxxxxxx openpkg@xxxxxxxxxxx OpenPKG-SA-2004.039 13-Sep-2004 ________________________________________________________________________ Package: kerberos Vulnerability: arbitrary code execution, denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= kerberos-1.3.4-20040730 >= kerberos-1.3.4-20040901 OpenPKG 2.1 <= kerberos-1.3.4-2.1.0 >= kerberos-1.3.4-2.1.1 OpenPKG 2.0 <= kerberos-1.3.1-2.0.1 >= kerberos-1.3.1-2.0.2 Dependent Packages: none Description: According to two vendor security advisories [1][2], multiple vulnerabilities exists in the Kerberos [0] network authentication system. The first set of problems are double-free issues in the KDC and libraries. The second problem is a denial-of-service vulnerability in the ASN.1 decoder. The Common Vulnerabilities and Exposures (CVE) project assigned the ids CAN-2004-0642 [3], CAN-2004-0643 [4], CAN-2004-0644 [5] and CAN-2004-0772 [6] to the problems. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q kerberos". If you have the "kerberos" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) [7][8]. Solution: Select the updated source RPM appropriate for your OpenPKG release [9][10], fetch it from the OpenPKG FTP service [11][12] or a mirror location, verify its integrity [13], build a corresponding binary RPM from it [7] and update your OpenPKG installation by applying the binary RPM [8]. 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 kerberos-1.3.4-2.1.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig kerberos-1.3.4-2.1.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild kerberos-1.3.4-2.1.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/kerberos-1.3.4-2.1.1.*.rpm ________________________________________________________________________ References: [0] http://web.mit.edu/kerberos/ [1] http://web.mit.edu/kerberos/www/advisories/MITKRB5-SA-2004-002-dblfree.txt [2] http://web.mit.edu/kerberos/www/advisories/MITKRB5-SA-2004-003-asn1.txt [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0642 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0643 [5] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0644 [6] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0772 [7] http://www.openpkg.org/tutorial.html#regular-source [8] http://www.openpkg.org/tutorial.html#regular-binary [9] ftp://ftp.openpkg.org/release/2.1/UPD/kerberos-1.3.4-2.1.1.src.rpm [10] ftp://ftp.openpkg.org/release/2.0/UPD/kerberos-1.3.1-2.0.2.src.rpm [11] ftp://ftp.openpkg.org/release/2.1/UPD/ [12] ftp://ftp.openpkg.org/release/2.0/UPD/ [13] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
