CURL-CVE-2022-27781 CERTINFO never-ending busy-loop

libcurl provides the CURLOPTCERTINFO option to allow applications to request details to be returned about a TLS server's certificate chain. Due to an erroneous function, a malicious server could make libcurl built with NSS get stuck in a never-ending busy-loop when trying to retrieve that...

CURL-CVE-2022-27779 cookie for trailing dot TLD

libcurl wrongly allows HTTP cookies to be set for Top Level Domains TLDs if the hostname is provided with a trailing dot. curl can be told to receive and send cookies when communicating using HTTPS. curl's "cookie engine" can be built with or without Public Suffix List awareness. If PSL support n...

TLS and SSH connection too eager reuse

libcurl would reuse a previously created connection even when a TLS or SSH related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, several TLS and...
