Summary
[none]
Details

When writing a long cookie name and value to a Netscape cookie jar, a remote HTTP server can make curl write a record that exceeds its line-length parsing limit. Consequently, any subsequent curl invocation reading from that same cookie jar using --cookie will silently abort parsing prematurely upon encountering the oversized line, ignoring all subsequent valid cookies in the file.
