Description

The remote host is affected by the vulnerability described in GLSA-202210-25 (ISC BIND: Multiple Vulnerabilities)

- In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing. (CVE-2021-25219)

- BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL.
The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. (CVE-2021-25220)

- BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period of time, even after the client has terminated the connection.
(CVE-2022-0396)

- By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.
(CVE-2022-2795)

- The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process. (CVE-2022-2881)

- An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service. (CVE-2022-2906)

- By sending specific queries to the resolver, an attacker can cause named to crash. (CVE-2022-3080)

- By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. (CVE-2022-38177)

- By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. (CVE-2022-38178)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All ISC BIND users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=net-dns/bind-9.16.33 All ISC BIND-tools users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=net-dns/bind-tools-9.16.33
