Bug ID: 3061
Summary: requesting invalid terminal modes no longer aborts
connection
Product: Portable OpenSSH
Version: 8.0p1
Hardware: All
OS: Linux
Status: NEW
Severity: minor
Priority: P5
Component: sshd
Assignee: unassigned-b...@mindrot.org
Reporter: mwhud...@debian.org
Created attachment 3312
--> https://bugzilla.mindrot.org/attachment.cgi?id=3312&action=edit
test case using golang.org/x/crypto
Running the attach test go test case against "OpenSSH_7.6p1
Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017" (i.e. Ubuntu 18.04)
yields:
2019/08/29 15:33:23 request for pseudo terminal failed: EOF
exit status 1
Running it against "OpenSSH_7.9p1 Ubuntu-10, OpenSSL 1.1.1b 26 Feb
2019" (i.e. Ubuntu 19.10) exits with code 0.
Going over the git history, it looks like this 1) could be a
consequence of the translation of ssh_tty_parse_modes to the sshbuf API
2) does not seem intentional.
