How to fix?

Upgrade Ubuntu:23.04 curl to version 7.88.1-8ubuntu2.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Ubuntu. See How to fix? for Ubuntu:23.04 relevant fixed versions and status.

When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API.

However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.
