Feldman" X-Sender: green@janus.syracuse.net To: security@FreeBSD.org Subject: another local DoS fix (PR ???) Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-security@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I can't find the PR for it again (it was from will@iki.fi, supposedly) for the problem, but this is something I have been working on crashopen.c and crashwrite.c had the ability to DoS a system easily. I fixed crashopen.c with the addition of badfileops. Crashwrite.c and other problems that could crop up like it are fixed by my patch up at http://www.FreeBSD.org/~green/fdfix2.patch Let me know how useful you find them. I'd like to get my diffs in 4.0 soon, since I've been running with them with no problems for months, and they make FreeBSD more robust. Let me know what you think, even if you don't try them, please :) -- Brian Fundakowski Feldman / "Any sufficiently advanced bug is \ green@FreeBSD.org | indistinguishable from a feature." | FreeBSD: The Power to Serve! \ -- Rich Kulawiec / To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
