Description

An advisory was sent out by the rsync team regarding a security vulnerability in all versions of rsync prior to and including 2.6.2. If rsync is running in daemon mode, and not in a chrooted environment, it is possible for a remote attacker to trick rsyncd into creating an absolute pathname while sanitizing it. This vulnerability allows a remote attacker to possibly read/write to/from files outside of the rsync directory.

The updated packages are patched to prevent this problem.
