I can tell you in general terms -- I don't write MIPS assembler myself. However, I will point out to you that you use an ancient Sendmail, and that it uses syslog(3) on user produced data, and that syslog uses a static buffer. Trick sendmail into logging something very big, and you can do what you like. The 8lgm people wrote a demo for Sparc as a proof of concept.
Hmm, after having looked at the syslogd code, it looks like this particular bug has been fixed for at least several years.
I said syslog(3), not syslogd(8). The bug is in the client, not the server. Yes, you suffer from it. Go and check.
However, there sure are a hell of a lot of fixed size buffers being alocated off the stack and some of them are being used in unsafe ways.
