Description

This security bulletin contains information about 5 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-4408)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when parsing DNS messages. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2023-50387)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation when processing DNSSEC related records. A remote attacker can trigger resource exhaustion by forcing the DNS server to query a specially crafted DNSSEC zone and perform a denial of service (DoS) attack.


3) Resource exhaustion (CVE-ID: CVE-2023-50868)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation when processing DNSSEC related records. A remote attacker can trigger resource exhaustion by forcing the DNS server to query a specially crafted DNSSEC zone and perform a denial of service (DoS) attack.


4) Reachable Assertion (CVE-ID: CVE-2023-5517)

CWE-ID: CWE-617 - Reachable Assertion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a reachable assertion when querying RFC 1918 reverse zones. A remote attacker can send a specially crafted DNS query and perform a denial of service attack.


5) Resource exhaustion (CVE-ID: CVE-2023-6516)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when processing specific recursive patterns. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack against the DNS resolver.
