SCA: security update for @ensdomains/ens-contracts (GHSA-rrxv-q8m4-wch3)

medium Tenable Self-Hosted Container Security Plugin ID 418919

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum
 blockchain. According to the documentation, controllers are allowed to register new domains and extend the
 expiry of existing domains, but they cannot change the ownership or reduce the expiration time of existing
 domains. However, a preliminary analysis suggests that an attacker-controlled controller may be able to
 reduce the expiration time of existing domains due to an integer overflow in the renew function. The
 vulnerability resides `@ensdomains/ens-contracts` prior to version 0.0.22. If successfully exploited, this
 vulnerability would enable attackers to force the expiration of any ENS record, ultimately allowing them
 to claim the affected domains for themselves. Currently, it would require a malicious DAO to exploit it.
 Nevertheless, any vulnerability present in the controllers could potentially render this issue exploitable
 in the future. An additional concern is the possibility of renewal discounts. Should ENS decide to
 implement a system that offers unlimited .eth domains for a fixed fee in the future, the vulnerability
 could become exploitable by any user due to the reduced attack cost. Version 0.0.22 contains a patch for
 this issue. As long as registration cost remains linear or superlinear based on registration duration, or
 limited to a reasonable maximum (eg, 1 million years), this vulnerability could only be exploited by a
 malicious DAO. The interim workaround is thus to take no action. (CVE-2023-38698)
