## Overview

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` silently aborts parsing prematurely upon
encountering the too long line, ignoring all subsequent valid cookies in the
file.

## Affected

- `curl >= 8.22.0 <= 8.22.0`
- `curl >= 8.21.0 <= 8.21.0`
- `curl >= 8.20.0 <= 8.20.0`
- `curl >= 8.19.0 <= 8.19.0`
- `curl >= 8.18.0 <= 8.18.0`
- `curl >= 8.17.0 <= 8.17.0`
- `curl >= 8.16.0 <= 8.16.0`
- `curl >= 8.15.0 <= 8.15.0`
- `curl >= 8.14.1 <= 8.14.1`
- `curl >= 8.14.0 <= 8.14.0`
- `curl >= 8.13.0 <= 8.13.0`
- `curl >= 8.12.1 <= 8.12.1`
- `curl >= 8.12.0 <= 8.12.0`
- `curl >= 8.11.1 <= 8.11.1`
- `curl >= 8.11.0 <= 8.11.0`
- `curl >= 8.10.1 <= 8.10.1`
- `curl >= 8.10.0 <= 8.10.0`
- `curl >= 8.9.1 <= 8.9.1`
- `curl >= 8.9.0 <= 8.9.0`
- `curl >= 8.8.0 <= 8.8.0`
- `curl >= 8.7.1 <= 8.7.1`
- `curl >= 8.7.0 <= 8.7.0`
