   1. Topic:
   
   New rsync packages are available; these fix a remotely exploitable problem
   in the I/O functions. These include the security patch from the recently
   released rsync-2.5.2. It is strongly recommended that all users of rsync
   upgrade to the fixed
   packages.
   2002-01-28: There was an error in the original bugfix patch for the
   security problem - the new rsync could fail under some circumstances. This
   has been fixed in a new build.
   
   2. Problem description:
   
   rsync is a powerful tool used for mirroring directory structures across
   machines. rsync has been found to contain several signed/unsigned bugs in
   its I/O functions which are remotely exploitable. A remote user can crash
   the rsync server/client and execute code as the user running the rsync
   server or client.
   The Common Vulnerabilities and Exposures project (cve.mitre.org) has
   assigned the name CAN-2002-0048 to this issue.
   All users of rsync should upgrade their packages. In addition rsync server
   administrators should consider using the "use chroot", "uid", and "read
   only" options, which can significantly reduce the impact of a security
   problem in rsync or elsewhere.
   Thanks go to Sebastian Krahmer for providing a patch for this vulnerability
   and to Andrew Tridgell and Martin Pool for their rapid response.
   
   3. Bug IDs fixed: (see bugzilla for more information)

   6. Solution:
   
   Before applying this update, make sure all previously released errata
   relevant to your system have been applied.
   To update all RPMs for your particular architecture, run:
   rpm -Fvh [filenames]
   where [filenames] is a list of the RPMs you wish to upgrade. Only those
   RPMs which are currently installed will be updated. Those RPMs which are
   not installed but included in the list will not be updated. Note that you
   can also use wildcards (*.rpm) if your current directory *only* contains the
   desired RPMs.
   Please note that this update is also available via Red Hat Network. Many
   people find this an easier way to apply updates. To use Red Hat Network,
   launch the Red Hat Update Agent with the following command:
   up2date
   This will start an interactive process that will result in the appropriate
   RPMs being upgraded on your system.
   
   7. Verification:
   
MD5 sum                           Package Name

   These packages are GPG signed by Red Hat, Inc. for security. Our key is available
   at:
   http://www.redhat.com/about/contact.html
   
   You can verify each package with the following command: rpm --checksig filename
   
   If you only wish to verify that each package has not been corrupted or tampered
   with, examine only the md5sum with the following command: rpm --checksig --nogpg
   filename
   
   Note that you need RPM >= 3.0 to check GnuPG keys.
