CVE-2021-22945

Disclosure Date: September 23, 2021 (last updated March 28, 2024)
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
