Vulnerability Details
CVEID: CVE-2022-2795
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by a flaw in resolver code. By flooding the target resolver with queries, a remote attacker could exploit this vulnerability to severely degrade the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.
CVSS Source: CVE.org
CVSS Base score: 5.3
CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-3094
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by the allocation of memory prior to the checking of access permissions (ACLs). By sending an UPDATE message flood, a remote attacker could exploit this vulnerability to cause named to exhaust all available memory.
CWE: CWE-416: Use After Free
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-3736
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by a flaw in the implementation of the stale-answer-client-timeout option. By sending RRSIG queries to the resolver, a remote attacker could exploit this vulnerability to cause named to crash when stale cache and stale answers are enabled.

CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-3924
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by a flaw in the implementation of the stale-answer-client-timeout option. By sending specific queries to the resolver, a remote attacker could exploit this vulnerability to cause named to crash.
CWE: CWE-617: Reachable Assertion
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-4408
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by an error when parsing large DNS messages. By flooding the target server with queries, a remote attacker could exploit this vulnerability to cause excessive CPU load.
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-5517
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by a flaw in query-handling code. By querying RFC 1918 reverse zones, a remote attacker could exploit this vulnerability to trigger an assertion failure.
CWE: CWE-617: Reachable Assertion
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-5679
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by an error when enabling both DNS64 and serve-stale. By querying a DNS64-enabled resolver for domain names triggering serve-stale, a remote attacker could exploit this vulnerability to trigger an assertion failure.
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-6516
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by an out-of-memory condition. By using specific recursive query patterns, a remote attacker could exploit this vulnerability to cause the amount of memory used by a named resolver to go well beyond the configured max-cache-size limit, leading to a denial of service.
CWE: CWE-770: Allocation of Resources Without Limits or Throttling
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-50387
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by an error when processing responses coming from specially crafted DNSSEC-signed zones. By flooding the target server with queries, a remote attacker could exploit this vulnerability to cause CPU exhaustion on a DNSSEC-validating resolver.
CWE: CWE-770: Allocation of Resources Without Limits or Throttling
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-50868
DESCRIPTION: ISC BIND is vulnerable to a denial of service, caused by an error when preparing an NSEC3 closest encloser proof. By flooding the target resolver with queries, a remote attacker could exploit this vulnerability to cause CPU exhaustion on a DNSSEC-validating resolver.
CWE: CWE-20: Improper Input Validation
CVSS Source: IBM X-Force
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
