XFree86-xfs-4.0.1-1 DoS

Hello, xfs from the package XFree86-xfs-4.0.1-1 (i386.rpm), RedHat 7.0 seems to suffer from a Denial of Service attack. To cause xfs to stop responding for requests, try to do the fillowing: $ telnet victim xfs </dev/urandom Repeat about 100 (or 1000) times and you get Connection refused message. Regular Xservers can no longer connect, usually crash stating Could not open default font 'fixed' and probably get disabled for 5 minutes if run from inittab. I'd appreciate any succesfull/unsuccesfull attemps of reproducing this behaviour. Regards, -- Valentine M. Smith
