{"id":"MGASA-2026-0541","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","modified":"2026-10-25T02:45:03.399174221Z","published":"2026-10-25T02:36:50Z","upstream":["CVE-2026-19630","CVE-2026-94300","CVE-2026-96888","CVE-2026-97313"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2026-0541.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=36559"},{"type":"WEB","url":"https://kb.isc.org/docs/cve-2026-19630"},{"type":"WEB","url":"https://kb.isc.org/docs/cve-2026-94300"},{"type":"WEB","url":"https://kb.isc.org/docs/cve-2026-96888"},{"type":"WEB","url":"https://kb.isc.org/docs/cve-2026-97313"}],"affected":[{"package":{"name":"bind","ecosystem":"Mageia:10","purl":"pkg:rpm/mageia/bind?arch=source&distro=mageia-10"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.20.30-1.1.mga10"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2026-0541.json"}}],"schema_version":"1.9.0","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
