This could be used to force the execution of a remote script and thus allow arbitrary command execution. Two CVE were assigned: CVE-2012-2251 Incorrect filtering of command line when using rsync protocol. It was for example possible to pass dangerous options after a "--" switch. The rsync protocol support has been added in a Debian (and Fedora/Red Hat) specific patch, so this vulnerability doesn't affect upstream. CVE-2012-2251 Incorrect filtering of the "--rsh" option: the filter preventing usage of the "--rsh=" option would not prevent passing "--rsh". This vulnerability affects upstream code. For the stable distribution (squeeze), this problem has been fixed in version 2.3.2-13squeeze2. For the testing distribution (wheezy), this problem has been fixed in version 2.3.3-6. For the unstable distribution (sid), this problem has been fixed in version 2.3.3-6. We recommend that you upgrade your rssh packages.
