[Bug 44175] New: stack corruption and crash with OpenSSH port
https://bugs.winehq.org/show_bug.cgi?id=44175 Bug ID: 44175 Summary: stack corruption and crash with OpenSSH port Product: Wine Version: 2.20 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: ossman(a)cendio.se Distribution: --- We have a port of OpenSSH to Windows that work well on a real Windows system, but crashes under Wine. I've tried to pinpoint the issue but I get very weird stack behaviours under winedbg. I've attached a binary with debug symbols. A simple "ssh.exe server.example.com" crashes. Stepping shows that the crash is on this code: sshconnect.c:641
if (sscanf(server_version_string, "SSH-%d.%d-%[^\n]\n", &remote_major, &remote_minor, remote_version) != 3)
However the stack is already corrupt when this code is reached. Stepping earlier in the program causes it to crap out when doing this call: ssh.c:1095
direct = option_clear_or_none(options.proxy_command) &&
options.proxy_command is NULL before the function is called, but once option_clear_or_none() the stack is bonkers with local variables and the call trace messed up. However it still executes a lot of code correctly after this, so it might just be a winedbg bug. Not sure how to proceed at this point. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
