Security

CVE-2024-8096: OCSP stapling bypass with GnuTLS When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine.

Changes

• –help [option]
• –skip-existing
• with -O, try harder to get a filename
• make –rate accept number of units. Previously it accepted N requests per single time unit, now it supports N requests per Z time units.
• make –show-headers the same as –include. To make the option name better spell out what it is for.
• –dump-header supports % to direct to stderr. To match a few of the other options that already support this.
• supports embedding a CA bundle and –dump-ca-embed. As this allows the curl tool to get built stand-alone without relying on an external CA store.
• supports repeated use of the verbose option; -vv etc.
• libuv for parallel transfers with –test-event. To allow better and easier testing of curl’s event-based API. Available in debug-builds only.
• add CURLINFO_POSTTRANSFER_TIME_T
• add –enable-windows-unicode configure option
• CURLOPT_TLS13_CIPHERS for mbedTLS and wolfSSL
• support for setting TLS version and ciphers for Rustls
• stop offering ALPN http/1.1 for http2-prior-knowledge
• support for sslcert/sslkey blob options for wolfSSL
• release tarball 100% reproducible. We also provide verify-release a convenient shell script allowing anyone and everyone to easily verify curl release tarballs.
