Description

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*.

Solution(s)

  • ubuntu-upgrade-curl
  • ubuntu-upgrade-libcurl3-gnutls
  • ubuntu-upgrade-libcurl3-nss
  • ubuntu-upgrade-libcurl4
