Updated bind package fixes security vulnerabilities

Publication date: 25 Oct 2026
Modification date: 25 Oct 2026
Type: security
Affected Mageia releases : 10
CVE: CVE-2026-19630 , CVE-2026-94300 , CVE-2026-96888 , CVE-2026-97313

Description

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