  script_tag(name:"insight", value:"The code that processes control channel messages sent to `named` calls
certain functions recursively during packet parsing. Recursion depth is
only limited by the maximum accepted packet size, depending on the
environment, this may cause the packet-parsing code to run out of
available stack memory, causing `named` to terminate unexpectedly. Since
each incoming control channel message is fully parsed before its
contents are authenticated, exploiting this flaw does not require the
attacker to hold a valid RNDC key, only network access to the control
channel's configured TCP port is necessary. (CVE-2023-3341)

A flaw in the networking code handling DNS-over-TLS queries may cause
`named` to terminate unexpectedly due to an assertion failure. This
happens when internal data structures are incorrectly reused under
significant DNS-over-TLS query load. (CVE-2023-4236)");
