CVE-2023-3341 3 Debian, Fedoraproject, Isc 3 Debian Linux, Fedora, Bind 2025-12-02 N/A 7.5 HIGH
The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1.
CVE-2023-50387 8 Fedoraproject, Isc, Microsoft and 5 more 13 Fedora, Bind, Windows Server 2008 and 10 more 2025-11-04 N/A 7.5 HIGH
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.
CVE-2022-38178 4 Debian, Fedoraproject, Isc and 1 more 4 Debian Linux, Fedora, Bind and 1 more 2025-05-28 N/A 7.5 HIGH
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-2022-38177 4 Debian, Fedoraproject, Isc and 1 more 4 Debian Linux, Fedora, Bind and 1 more 2025-05-28 N/A 7.5 HIGH
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-2022-2906 1 Isc 1 Bind 2025-05-28 N/A 7.5 HIGH
An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.
CVE-2022-2881 1 Isc 1 Bind 2025-05-28 N/A 5.5 MEDIUM
The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process.
CVE-2018-5733 4 Canonical, Debian, Isc and 1 more 8 Ubuntu Linux, Debian Linux, Dhcp and 5 more 2025-04-25 5.0 MEDIUM 7.5 HIGH
