Synopsis
The remote Amazon Linux 2022 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-166 advisory.A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. This issue causes it to obtain and pass on potentially incorrect answers. This flaw allows a remote attacker to manipulate cache results with incorrect records, leading to queries made to the wrong servers, possibly resulting in false information received on the client's end. (CVE-2021-25220)
A flaw was found in Bind that incorrectly handles certain crafted TCP streams. The vulnerability allows TCP connection slots to be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. This flaw allows a remote attacker to send specially crafted TCP streams with keep- response-order enabled that could cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period, even after the client has terminated the connection. This issue results in BIND consuming resources, leading to a denial of service. (CVE-2022-0396)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
