CVE-2023-2828

Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets from the cache, to keep memory use below the configured limit. It has been discovered that the effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0 through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.

- MitigationARM600abb_psirt
Mitigating factors describe conditions and circumstances that make an attack that exploits the vulnerability difficult or less likely to succeed. The following mitigations are recommended. 3. ARM600 system is by default not dependent on the name service (DNS). If name service is not used in the system, the name service port (TCP/UDP port 53) can be blocked by a firewall. Refer to section General security recommendations for additional advice on how to keep your system secure.

- 2NGA002579ABB Arctic communication solution ARM600 Vulnerabilities2025-04-07csaf · abb_psirtCH
ABB is aware of public reports of a vulnerabilities in product versions listed as affected in this advisory. An attacker who successfully exploited these vulnerabilities could cause the product to stop, make the product inacces-sible, take remote control of the product or insert and run arbitrary code. As part of ABB product lifecycle policy, once a product transitions to end-of-life, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document, such as using a private APN cellular network between Arctic wireless gateways and ARM600 for establishing VPN tunnels, to mitigate security risks and avoid potential vulnerabilities. As part of ABB product lifecycle policy, once a product transitions to Limited state, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document to mitigate security risks.
