Package:             rsync
Vulnerability:       filesystem path determination
OpenPKG Specific:    no

Affected Releases:   Affected Packages:       Corrected Packages:
OpenPKG CURRENT      <= rsync-2.6.2-20040706  >= rsync-2.6.2-20040815
OpenPKG 2.1          <= rsync-2.6.2-2.1.0     >= rsync-2.6.2-2.1.1
OpenPKG 2.0          <= rsync-2.6.0-2.0.1     >= rsync-2.6.0-2.0.2

Dependent Packages:  none

Description:
  According to a security notice [1] by the vendor, a path-sanitizing
  bug exists in the filesystem synchronization utility RSYNC [2]. The
  bug affects daemon mode in all RSYNC versions up to and including
  2.6.2 if option "use chroot" is disabled (not the case in the default
  configuration in OpenPKG). It does not affect the normal send/receive
  filenames that specify what files should be transferred, but it does
  affect certain option paths that cause auxilliary files to be read or
  written.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  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) and its dependent packages (see above), if
  any, too [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 2.1, 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 rsync-2.6.2-2.1.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig rsync-2.6.2-2.1.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild rsync-2.6.2-2.1.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/rsync-2.6.2-2.1.1.*.rpm
