An exploit + is known to be in the wild and the security of a public rsync was + compromised. A successful attack does not directly lead to root access + but can be combined with other local exploits. The do_brk vulnerbility + in Linux kernels prior 2.4.23 is worthwhile to mention these days. 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 "<prefix>/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 + $ <prefix>/bin/rpm -v --checksig rsync-2.5.6-1.3.1.src.rpm + $ <prefix>/bin/rpm --rebuild rsync-2.5.6-1.3.1.src.rpm + $ su - + # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/rsync-2.5.6-1.3.1.*.rpm +________________________________________________________________________ + +References: + [0] http://marc.theaimsgroup.com/?l=rsync-announce&m=107051741303720 + [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 <[EMAIL PROTECTED]>" (ID 63C4CB9F) of the +OpenPKG project which you can retrieve from http://pgp.openpkg.org and +hkp://pgp.openpkg.org.
