    Package : rssh
    Vulnerability : insufficient filtering of rsync command line
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2012-2251 CVE-2012-2252
    Debian Bug :

    James Clawson discovered that rssh, a restricted shell for OpenSSH to be used with scp/sftp, rdist and cvs, was not correctly filtering command line options. 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.
