Synopsis

Moderate: bind9.16 security and bug fix update

Type/Severity

Security Advisory Moderate

Topic

An update for bind9.16 is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

Security Fix(es):

  • bind: processing large delegations may severely degrade resolver performance (CVE-2022-2795)

  • bind: flooding with UPDATE requests may lead to DoS (CVE-2022-3094)

  • bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3736)

  • bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3924)
