Ticket #67 (closed defect)
Unable to re-exchange keys with openssh
|Reported by:||anonymous||Owned by:||bagder|
When using sftp client to upload a very large file (mine is roughly 3 GB) libssh goes into an infinite loop. I've had this occur using several sshd servers including openssh. The crash is due to a stack overflow.
This is the constant backtrace:
It's easier to repro this if you tweak openssh sshd.c to cause key re-exchange sooner. Currently the settings are after ~1 GB of data xfered. The reccomended settings in the RFC.(http://www.ietf.org/rfc/rfc4253.txt)
Any help would be greatly appreciated.
