When a protocol selection parameter option disables all protocols without adding any then the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols. The below command would perform a request to curl.se with a plaintext protocol which has been explicitly disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols disables the entire set of available protocols, in itself a command with no practical use and therefore unlikely to be encountered in real situations. The curl security team has thus assessed this to be low severity bug.

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2693 advisory.

  - When a protocol selection parameter option disables all protocols without adding any then the default set     of protocols would remain in the allowed set due to an error in the logic for removing protocols. The     below command would perform a request to curl.se with a plaintext protocol which has been explicitly     disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols     disables the entire set of available protocols, in itself a command with no practical use and therefore     unlikely to be encountered in real situations. The curl security team has thus assessed this to be low     severity bug. (CVE-2024-2004)

  - libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to     use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the     verification and returns OK, thus ignoring any certificate problems. (CVE-2024-2379)

  - When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers     for the push surpasses the maximum allowed limit (1000), libcurl aborts the server push. When aborting,     libcurl inadvertently does not free all the previously allocated headers and instead leaks the memory.
    Further, this error condition fails silently and is therefore not easily detected by an application.
    (CVE-2024-2398)

  - libcurl did not check the server certificate of TLS connections done to a host specified as an IP address,     when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified     hostname was given as an IP address, therefore completely skipping the certificate check. This affects all     uses of TLS protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc). (CVE-2024-2466)

  - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an     informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
    (CVE-2024-27316)

  - nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior     to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is     reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2     v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
    There is no workaround for this vulnerability. (CVE-2024-28182)
