Debian: DLA-2816-1 Critical: Icinga2 Multiple Threats Detected

CVE-2021-32739

A vulnerability exists that may allow privilege escalation for
authenticated API users. With a read-ony user's credentials, an
attacker can view most attributes of all config objects including
`ticket_salt` of `ApiListener`. This salt is enough to compute a
ticket for every possible common name (CN). A ticket, the master
node's certificate, and a self-signed certificate are enough to
successfully request the desired certificate from Icinga. That
certificate may in turn be used to steal an endpoint or API user's
identity. See also complementary manual procedures:

CVE-2021-32743

Some of the Icinga 2 features that require credentials for
external services expose those credentials through the API to
authenticated API users with read permissions for the
corresponding object types. IdoMysqlConnection and
