.netrc parser out-of-bounds access

curl can be told to parse a .netrc file for credentials. If that file ends in a line with consecutive non-white space letters and no newline, curl could read past the end of the stack-based buffer, and if the read works, write a zero byte possibly beyond its boundary. This does in most cases caus...

HTTP proxy double free

If curl is told to use an HTTP proxy for a transfer with a non-HTTPS URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of protocol through. An HTTP proxy might refuse this request HTTP proxies often only allow outgoing...

In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS support, curl can be instructed to use HTTPS directly instead of using an insecure cleartext HTTP step even when HTTP is provided in the URL. This mechanism could be bypassed if the host nam...
