Recursion depth is\nonly limited by the maximum accepted packet size; depending on the\nenvironment, this may cause the packet-parsing code to run out of\navailable stack memory, causing `named` to terminate unexpectedly. Since\neach incoming control channel message is fully parsed before its\ncontents are authenticated, exploiting this flaw does not require the\nattacker to hold a valid RNDC key; only network access to the control\nchannel's configured TCP port is necessary. (CVE-2023-3341)\n\nA flaw in the networking code handling DNS-over-TLS queries may cause\n`named` to terminate unexpectedly due to an assertion failure. This\nhappens when internal data structures are incorrectly reused under\nsignificant DNS-over-TLS query load.
