There are also parsing problems in the ASN.1 library used by OpenSSL. The Common Vulnerabilities and Exposures (CVE) project assigned the ids CAN-2002-0655 [6], CAN-2002-0656 [7], CAN-2002-0657 [8] and CAN-2002-0659 [9] to the problems. Several of these vulnerabilities could be used by a remote attacker to execute arbitrary code on the target system. All could be used to create a denial of service. Please check whether you are affected by running "<prefix>/bin/rpm -q openssl". If you have the "openssl" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution). Additionally, you have to rebuild and reinstall all dependent OpenPKG packages, too. [2] Solution: Select the updated source RPM appropriate for your OpenPKG release [4], fetch it from the OpenPKG FTP service [3] or a mirror location, verify its integrity [1], build a corresponding binary RPM from it and update your OpenPKG installation by applying the binary RPM [2]. For the latest OpenPKG 1.0 release, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.0/UPD ftp> get openssl-0.9.6b-1.0.1.src.rpm ftp> bye $ <prefix>/bin/rpm --checksig openssl-0.9.6b-1.0.1.src.rpm $ <prefix>/bin/rpm --rebuild openssl-0.9.6b-1.0.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.6b-1.0.1.*.rpm Now proceed and rebuild and reinstall all dependent OpenPKG packages, too (see list above). ________________________________________________________________________ References: [1] http://www.openpkg.org/security.html#signature [2] http://www.openpkg.org/tutorial.html#regular-source [3] ftp://ftp.openpkg.org/release/1.0/UPD/ [4] ftp://ftp.openpkg.org/release/1.0/UPD/openssl-0.9.6b-1.0.1.src.rpm [5] http://www.openssl.org/news/secadv_20020730.txt [6] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0655 [7] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0656 [8] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0657 [9] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0659 ________________________________________________________________________ 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/.
