Details

Dan Fandrich discovered that curl would incorrectly use the default set of
protocols when a parameter option disabled all protocols without adding
any, contrary to expectations. This issue only affected Ubuntu 23.10.
(CVE-2024-2004)

It was discovered that curl incorrectly handled memory when limiting the
amount of headers when HTTP/2 server push is allowed. A remote attacker
could possibly use this issue to cause curl to consume resources, leading
to a denial of service. (CVE-2024-2398)
