Details
USN-6718-1 fixed a vulnerability in curl. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
Original advisory details:
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)
