This is a copy of a report I sent to the CERT some time ago about Highland's FLEXlm software. I've removed the Sun engineer's name from the included message in case anyone decides to blame the messenger. The following is a description of what I believe to be a serious vulnerability in the widely used FLEXlm network licensing package written by Highland Software. Alpha is running the FLEXlm licence server software.
Beta has a copy of the FLEXlm software too, and in particular has the lmdown program.
