April 27, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.10
- Ubuntu 10.04 LTS

It was discovered that rsync incorrectly handled memory when certain
recursion, deletion and ownership options were used. If a user were tricked
into connecting to a malicious server, a remote attacker could cause a
denial of service or execute arbitrary code with privileges of the user
invoking the program.
The problem can be corrected by updating your system to the following
Ubuntu 10.04 LTS:
In general, a standard system update will make all the necessary changes.
