  "summary": "Updated bind package fixes security vulnerabilities",
  "details": "* In a BIND resolver, inbound DNS protocol messages with a particular\nstructure will result in additional processing, with no limit imposed by\nBIND. A DNS message with a maliciously large number of such structures\nwill cause BIND to consume disproportionate amounts of CPU time and\nmemory during processing (CVE-2026-19630).\n* Replaying GSS-TSIG signed UDP messages can result in memory corruption\nin \"named\". An attacker who can capture a previously signed UDP message\ncan replay it while the negotiated TSIG key is still valid. By also\nsending crafted queries to a zone the attacker controls, the attacker\nmay potentially achieve remote code execution (CVE-2026-94300).\n* A BIND resolver that is configured with both a \"redirect\" zone and\n\"qname-minimization strict\" may abort with an assertion failure while\nprocessing the redirect (CVE-2026-96888).\n* A recursive BIND server that receives a query with recursion desired\n(RD=1) followed by a non-recursive query (RD=0) may exit with an\nassertion failure, resulting in a denial of service. To be vulnerable,\nthe BIND server must allow recursive queries and have at least two RPZ\nzones configured: one with the default setting of \"recursive-only yes\",\nand the other with \"recursive-only no\" (CVE-2026-97313).\n",
