-----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-2003.051 04-Dec-2003 ________________________________________________________________________ Package: rsync Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= rsync-2.5.6-20030807 >= rsync-2.5.7-20031204 OpenPKG 1.3 <= rsync-2.5.6-1.3.0 >= rsync-2.5.6-1.3.1 OpenPKG 1.2 <= rsync-2.5.5-1.2.0 >= rsync-2.5.5-1.2.1 Dependent Packages: none Description: According to a rsync security advisory [0], a heap overflow vulnerability exists in rsync [1] version 2.5.6 and earlier when used as a rsync server which typically listens on TCP port 873. An exploit is already known. A successful attack can lead to arbitrary code execution in the run-time environment of the rsync server process. The attack is known to be considerably easier when the "use chroot = no" option is set in rsync.conf, which is not the default in OpenPKG. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0962 [2] to the problem. Please check whether you are affected by running "/bin/rpm -q rsync". If you have the "rsync" 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 current release OpenPKG 1.3, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.3/UPD ftp> get rsync-2.5.6-1.3.1.src.rpm ftp> bye $ /bin/rpm -v --checksig rsync-2.5.6-1.3.1.src.rpm $ /bin/rpm --rebuild rsync-2.5.6-1.3.1.src.rpm $ su - # /bin/rpm -Fvh /RPM/PKG/rsync-2.5.6-1.3.1.*.rpm ________________________________________________________________________ References: [0] http://marc.theaimsgroup.com/?l=rsync-announce&m=10705174130372 0 [1] http://rsync.samba.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0962 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.2/UPD/rsync-2.5.5-1.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.3/UPD/rsync-2.5.6-1.3.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.2/UPD/ [8] ftp://ftp.openpkg.org/release/1.3/UPD/ [9] 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.
