Security Fixes
~~~~~~~~~~~~~~
- [CVE-2026-11331] Fix handling of rpz CNAME expansion that returns name
too long. ``
b950da5f625``
Previously, if the expansion of a wildcard CNAME RPZ policy resulted
in a name that exceeded the length limit, a self referential CNAME and
the original address record were returned, allowing the policy to be
bypassed. In branches up to 9.20, this also left query processing in
an inconsistent state which could trigger an assertion failure. We
now return a YXDOMAIN response, without the address.
ISC would like to thank Laith Mash'al (0xmshal) for bringing this
issue to our attention. :gl:`#5856`
- [CVE-2026-11721] Invalid signed wildcard records were being accepted.
``
249752cd72d``
Signed wildcard responses in which the Labels field in the `RRSIG`
record was less than the number of labels in the Signer Name field
were being incorrectly accepted. This in turn broke
`synth-from-dnssec`, which depends on such records being correctly
validated. This has been fixed.
ISC thanks Qifan Zhang of Palo Alto Networks for bringing this issue
to our attention. :gl:`#5871`
- [CVE-2026-13321] Fix DNSSEC validation bypass via out-of-zone NSEC
Next Field. ``
6fbc963d4af``
A malicious zone with out-of-zone NSEC next owner names can cause a
DNSSEC validating resolver to cache such record and, if
`synth-from-dnssec` is enabled, to generate negative answers for any
zone that is covered by the range.
ISC would like to thank Qifan Zhang of Palo Alto Networks for
reporting the issue. :gl:`#5873`
- [CVE-2026-10723] Correct verification of NSEC3 signer name.
``
df3abfc3184``
BIND 9 accepted child-zone NSEC3 records where the first label equals
the hash of the parent zone as valid parent-zone closest encloser
proofs. This has been fixed.
ISC thanks Qifan Zhang of Palo Alto Networks for reporting the issue.
:gl:`#5874`
- [CVE-2026-12617] Do no assert for some specifics CNAME and DNAME
queries. ``
d75d1e93958``
A bug in the resolver's handling of certain cached DNAME and CNAME
responses could cause named to trigger an assertion failure and exit.
An attacker controlling a domain name and the authoritative DNS server
it is hosted on could exploit this behavior to cause a
denial-of-service. This vulnerability has been fixed.
ISC thanks Qifan Zhang of Palo Alto Networks for bringing this issue
to our attention. :gl:`#5946`
- [CVE-2026-10822] Malformed DNSKEY records could trigger an assertion.
``
a1777ce7ee0``
Previously, `dns_name_fromwire()` did not honor the record boundary
when reading names from the wire, allowing malformed records to be
accepted when they should not have been
