Hello Josh, Steve, vendors, based on Debian BTS report: [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=628843 (first CVE-2011-XXYY required for Debian case) looked more into original report: [2] https://bugzilla.redhat.com/show_bug.cgi?id=173008 and the first paragraph of [2] suggests: "When starting a program via "su - user -c program" the user session can escape to the parent session by using the TIOCSTI ioctl to push characters into the input buffer. This allows for example a non-root session to push "chmod 666 /etc/shadow" or similarly bad commands into the input buffer such that after the end of the session they are executed." this should get a CVE-2005-YYZZ CVE id. Could you allocate these?
