Fortunately he put the only correct response to this nonsense right in there - saves me some typing. Quote from the varnish team:<p>This is not a security problem in Varnish or any other piece of software
which writes a logfile.<p>The real problem is the mistaken belief that you can cat(1) a random
logfile to your terminal safely.<p>This is not a new issue. I first remember the issue with xterm(1)'s
inadvisably implemented escape-sequences in a root-context, brought up
heatedly, in 1988, possibly late 1987, at Copenhagens University
Computer Science dept. (Diku.dk). Since then, nothing much have changed.<p>The wisdom of terminal-response-escapes in general have been questioned
at regular intervals, but still none of the major terminal emulation
programs have seen fit to discard these sequences, probably in a
misguided attempt at compatibility with no longer used 1970'es
technology.<p>I admit that listing "found a security hole in all HTTP-related programs
that write logfiles" will look more impressive on a resume, but I think
it is misguided and a sign of trophy-hunting having overtaken common
sense.<p>Instead of blaming any and all programs which writes logfiles, it would
be much more productive, from a security point of view, to get the
terminal emulation programs to stop doing stupid things, and thus fix
this and other security problems once and for all.
