This seems to be happening in a few locations, but I haven't been able to repro it here yet, not even with valgrind. The dump makes it looks like a sshcipher_ctx struct has been partially overwritten with garbage. In cipher_free() it crashes on this line:
if ((cc->cipher->flags & CFLAG_CHACHAPOLY) != 0) {
...because cc->cipher points to a bad location (but it's not NULL). Questions: 1) Do you know more precisely when this started happening? I'm suspecting patches added to openssh or openssl this autumn. 2) Could you run sshd like this (as root): /usr/sbin/sshd -Dddd -p 2048 Then from a different shell session, connect to it like this: ssh localhost -p 2048 ...and trigger the crash, then attach the sshd debug output here? -- You are receiving this mail because: You are on the CC list for the bug.
