[auth-options.c auth1.c auth2.c bufaux.c buffer.h kex.c key.c packet.c] [packet.h ssh-dss.c ssh-rsa.c] Add buffer_get_cstring() and related functions that verify that the string extracted from the buffer contains no embedded \0 characters* This prevents random (possibly malicious) crap from being appended to strings where it would not be noticed if the string is used with a string(3) function. Use the new API in a few sensitive places. * actually, we allow a single one at the end of the string for now because we don't know how many deployed implementations get this wrong, but don't count on this to remain indefinitely.

[auth1.c auth2-none.c] skip the initial check for access with an empty password when PermitEmptyPasswords=no; bz#1638; ok markus@

auth2-pubkey.c session.c openbsd-compat/bsd-cygwin_util.{c,h} openbsd-compat/daemon.c] Remove support for Windows 95/98/ME and very old version of Cygwin. Patch from vinschen at redhat com.
2008-07-09 - (djm) [auth1.c] Fix format string vulnerability in protocol 1 PAMDamien Miller
account check failure path. The vulnerable format buffer is supplied from PAM and should not contain attacker-supplied data.

[auth1.c auth2.c] Make protocol 1 MaxAuthTries logic match protocol 2's. Do not treat the first protocol 2 authentication attempt as a failure IFF it is for method "none". Makes MaxAuthTries' user-visible behaviour identical for protocol 1 vs 2. ok dtucker@

[auth-options.c auth1.c channels.c channels.h clientloop.c gss-serv.c] [monitor.c monitor_wrap.c nchan.c servconf.c serverloop.c session.c] [ssh.c sshd.c] Implement a channel success/failure status confirmation callback mechanism. Each channel maintains a queue of callbacks, which will be drained in order (RFC4253 guarantees confirm messages are not reordered within an channel). Also includes a abandonment callback to clean up if a channel is closed without sending confirmation messages. This probably shouldn't happen in compliant implementations, but it could be abused to leak memory. ok markus@ (as part of a larger diff)
