Synopsis

The remote Slackware Linux host is missing a security update to bind.

Description

The version of bind installed on the remote host is prior to 9.16.33 / 9.18.7. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-264-01 advisory.

 - 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)

 - 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)
