USN-1124-1: rsync vulnerability

27 April 2011

rsync could be made to crash or run programs as your login if it connected to a malicious server.



  • rsync - fast remote file copy program (like rcp)


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10
Ubuntu 10.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
