Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Reachable Assertion
EUVDB-ID: #VU52734
Risk: Low
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-25214
CWE-ID:
CWE-617 - Reachable Assertion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when pressing IXFR queries. An IXFR stream containing SOA records with an owner name other than the transferred zone's apex may cause the receiving named
server to inadvertently remove the SOA record for the zone in question
from the zone database. This leads to an assertion failure when the next
SOA refresh query for that zone is made. When a vulnerable version of named receives a malformed IXFR triggering the flaw described above, the named process will terminate due to a failed assertion the next time the transferred secondary zone is refreshed.
Update the affected package bind to the latest version.

2) Reachable Assertion
EUVDB-ID: #VU52736
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-25215
CWE-ID:
CWE-617 - Reachable Assertion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when processing DNAME records. A remote attacker can force named to add the same RRset to the ANSWER section more than once, trigger an assertion failure and crash the service. Both authoritative and recursive servers are affected by this issue during zone transfers.
Update the affected package bind to the latest version.

3) Buffer overflow
EUVDB-ID: #VU52737
Risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-25216
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the GSS-TSIG extension. A remote attacker can send specially crafted requests to the server, trigger buffer overflow and execute arbitrary code on the system.
Successful exploitation of the vulnerability requires that named is configure to use SPNEGO implementation by setting values for the tkey-gssapi-keytab or tkey-gssapi-credential configuration options (often used with Samba as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers).
Update the affected package bind to the latest version.
