Bug #16886 for Net-SSH2: scp_get dies with a Segmentation fault

Tue Jan 03 10:17:53 2006 Guest - Ticket created

Subject:

scp_get dies with a Segmentation fault

scp_get will cause a Segmentation fault when reading 'large' files. If a file has more than 65536 bytes (64k) the program will die. This behaviour is identical under debian (sarge) and ubuntu(breezy) both with libssh2 version 0.12.

I'm having the same problems, I'm also getting the error with Net::SSH2 0.06

I'm able to scp_get files over 64k with no problems; can you provide a core dump (you can send it directly to my CPAN address if you prefer). The code I just used to test it was: perl -MNet::SSH2 -wle '$a=Net::SSH2->new();$a->connect("HOSTNAME");$a->auth_keyboard("USER"=>"PASSWORD") or die;$c=$a->scp_get("TRIAL64K")' Then I diff'd it with the original and it matched.

Here is the core file that I get when executing scp_get. The other file, 'data.txt', is the sample data i was trying to send.

Message body is not shown because it is too large.

Download core
application/octet-stream 3.2m

Message body not shown because it is not plain text.

This time I tried the transfer with the version 0.06 of Net::SSH2. libssh2 is still at the same version 0.12. The SSH server responded with: SSH-2.0-OpenSSH_4.1p1 Debian-7ubuntu4

Fixed in 0.07 (the terminating null was written outside the buffer).
