Disallow leading lines before the ident for server (#102)
Per RFC4253 4.2 clients must be able to process other lines of data
before the version string, server behavior is not defined neither
with MUST/SHOULD nor with MAY.
If server process up to 50 lines too - it may cause too long hanging
session with invalid/evil client that consume host resources and
potentially may lead to DDoS on poor embedded boxes.
Let's require first line from client to be version string and fail
early if it's not - matches both RFC and real OpenSSH behavior.

Building with the diet libc --------------------------- This package optionally can be built with the diet libc instead of the glibc to provide small statically linked programs. The resulting package has no dependency on any other package. To use the diet libc, make sure the latest versions of the dietlibc-dev package is installed, and set DEB_BUILD_OPTIONS=diet in the environment when building the package, e.g.: # apt-get install dietlibc-dev $ DEB_BUILD_OPTIONS=diet fakeroot apt-get source -b dropbear -- Gerrit Pape <[email protected]>, Sat, 17 Jul 2004 19:09:34 +0000
