  "title": "unbound: NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain...",
  "description": "NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain-name operation but has no aggregate inbound decompression-work budget. Many chained compression pointers in a message results in a lot of CPU usage following them. A malicious actor with recursive-query access and control of an ordinarily delegated authority that serves specially crafted replies can exploit the vulnerability and degrade Unbound\u0027s general performance.",
