Ubuntu Security Notice USN-1124-1
27th April, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 9.10
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 10.10:
- rsync 3.0.7-2ubuntu1.1
- Ubuntu 10.04 LTS:
- rsync 3.0.7-1ubuntu1.1
- Ubuntu 9.10:
- rsync 3.0.6-1ubuntu1.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
