Summary
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.
