"description": "Authoritative-only BIND 9 servers are NOT vulnerable to this flaw. The purpose of a resolver\u0027s lame cache is to ensure that if an authoritative server responds to a resolver\u0027s query in a specific broken way, subsequent client queries for the same \u003cQNAME, QTYPE\u003e tuple do not trigger further queries to the same server for a configurable amount of time. The lame cache is enabled by setting the \"lame-ttl\" option in named.conf to a value greater than 0. That option is set to \"lame-ttl 600;\" in the default configuration, which means the lame cache is enabled by default. A successful attack exploiting this flaw causes a named resolver to spend most of its CPU time on managing and checking the lame cache. This results in client queries being responded to with large delays, and increased likelihood of DNS timeouts on client hosts. Affects BIND 9.3.0 -\u003e 9.11.35, 9.12.0 -\u003e 9.16.21, and versions 9.9.3-S1 -\u003e 9.11.35-S1 and 9.16.8-S1 -\u003e 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -\u003e 9.17.18 of the BIND 9.17 development branch.",

This corrects CVE-2021-25216, but requires that the system have other libraries and header files to support GSS-TSIG functionality, unless such functionality is completely disabled at build time by providing the --without-gssapi argument to the ./configurescript when selecting build options."

"value": "This vulnerability only affects servers configured to use GSS-TSIG, most often to sign dynamic updates. If another mechanism can be used to authenticate updates, the vulnerability can be avoided by choosing not to enable the use of GSS-TSIG features.\n\nPrior to the April 2021 BIND releases, on some platforms it was possible to build a working BIND installation that was not vulnerable to CVE-2021-25216 by providing the --disable-isc-spnego command-line argument when running the ./configure script in the top level of the BIND source directory, before compiling and linking named.\n\nAfter the April 2021 BIND releases, all supported branches have removed isc-spnego support. This corrects CVE-2021-25216, but requires that the system have other libraries and header files to support GSS-TSIG functionality, unless such functionality is completely disabled at build time by providing the --without-gssapi argument to the ./configurescript when selecting build options."
