-----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-2005.022 17-Oct-2005 ________________________________________________________________________ Package: openssl Vulnerability: potential SSL 2.0 rollback OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= openssl-0.9.8-2005092 >= openssl-0.9.8a-20051011 OpenPKG 2.4 <= openssl-0.9.7g-2.4.1 >= openssl-0.9.7g-2.4.2 OpenPKG 2.3 <= openssl-0.9.7e-2.3.2 >= openssl-0.9.7e-2.3.3 Dependent Packages: unknown Description: According to a vendor security advisory [0], a potential SSL 2.0 protocol rollback attack vulnerability exists in the cryptography toolkit OpenSSL [1]. The vulnerability potentially affects applications that use the SSL/TLS server implementation provided by OpenSSL. Such applications are affected if they use the option "SSL_OP_MSIE_SSLV2_RSA_PADDING". Applications using neither "SSL_OP_MSIE_SSLV2_RSA_PADDING" nor "SSL_OP_ALL" are not affected. Also, applications that disable use of SSL 2.0 are not affected. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2969 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg 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) [3][4]. Solution: Select the updated source RPM appropriate for your OpenPKG release [5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror location, verify its integrity [9], build a corresponding binary RPM from it [3] and update your OpenPKG installation by applying the binary RPM [4]. For the most recent release OpenPKG 2.4, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.4/UPD ftp> get openssl-0.9.7g-2.4.2.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig openssl-0.9.7g-2.4.2.src.rpm $ <prefix>/bin/openpkg rpm --rebuild openssl-0.9.7g-2.4.2.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.7g-2.4.2.*.rpm ________________________________________________________________________ References: [0] http://www.openssl.org/news/secadv_20051011.txt [1] http://www.openssl.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2969 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.4/UPD/openssl-0.9.7g-2.4.2.src.rpm [6] ftp://ftp.openpkg.org/release/2.3/UPD/openssl-0.9.7e-2.3.3.src.rpm [7] ftp://ftp.openpkg.org/release/2.4/UPD/ [8] ftp://ftp.openpkg.org/release/2.3/UPD/ [9] 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.
