Denis Sokolov commented on PROTON-560:
--------------------------------------
Ken, you will laugh, but it is me again.
The main issue wasn't the incorrect size. The main issue is that we overwrite
new allocated memory with garbage, because _*data*_ pointer points to released
memory and we use it here:
{noformat}
if (ssl->in_count > 0 && data != ssl->inbuf)
memmove( ssl->inbuf, data, ssl->in_count );
{noformat}
Correct fix looks like that (last string):
{noformat}
ssl->in_size = max_frame;
memmove( newbuf, ssl->inbuf, ssl->in_count );
free( ssl->inbuf );
ssl->inbuf = newbuf;
data = ssl->inbuf;
{noformat}
And Margarita have pointed to that string.
