New rsync release
In response we have released a new version of rsync, version 2.5.7. This is based on the current stable 2.5.6 release with only the changes necessary to prevent this heap overflow vulnerability. There are no new features in this release.

We recommend that anyone running a rsync server take the following steps:

Update to rsync version 2.5.7 immediately.
If you are running a Linux kernel prior to version 2.4.23 then you should upgrade your kernel immediately. Note that some distribution vendors may have patched versions of the 2.4.x series kernel that fix the brk vulnerability in versions before 2.4.23. Check with your vendor security site to ensure that you are not vulnerable to the brk problem.
Review your /etc/rsyncd.conf configuration file. If you are using the option "use chroot = no" then remove that line or change it to "use chroot = yes". If you find that you need that option for your rsync service then you should disable your rsync service until you have discussed a workaround with the rsync maintainers on the rsync mailing list. The disabling of the chroot option should not be needed for any normal rsync server.
The patches and full source for rsync version 2.5.7 are available from http://rsync.samba.org/ and mirror sites. We expect that vendors will produce updated packages for their distributions shortly.
