SUSE CVE-2020-24334

The code that processes DNS responses in uIP through 1.0, as used in Contiki and Contiki-NG, does not check whether the number of responses specified in the DNS packet header corresponds to the response data available in the DNS packet, leading to an out-of-bounds read and Denial-of-Service in...

SUSE CVE-2020-24340

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The code that processes DNS responses in picomdnshandledataasanswersgeneric in picomdns.c does not check whether the number of answers/responses specified in a DNS packet header corresponds to the response data available in the...

SUSE CVE-2020-24339

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The DNS domain name record decompression functionality in picodnsdecompressname in picodnscommon.c does not validate the compression pointer offset values with respect to the actual data present in a DNS response packet, causing...

SUSE CVE-2020-24383

An issue was discovered in FNET through 4.6.4. The code for processing resource records in mDNS queries doesn't check for proper '\0' termination of the resource record name string, leading to an out-of-bounds read, and potentially causing information leak or Denial-or-Service...

SUSE CVE-2020-25107

An issue was discovered in the DNS implementation in Ethernut in Nut/OS 5.1. There is no check on whether a domain name has '\0' termination. This may lead to successful Denial-of-Service, and possibly Remote Code Execution...

SUSE CVE-2020-25110

An issue was discovered in the DNS implementation in Ethernut in Nut/OS 5.1. The length byte of a domain name in a DNS query/response is not checked, and is used for internal memory operations. This may lead to successful Denial-of-Service, and possibly Remote Code Execution...

SUSE CVE-2020-25109

An issue was discovered in the DNS implementation in Ethernut in Nut/OS 5.1. The number of DNS queries/responses set in a DNS header is not checked against the data present. This may lead to successful Denial-of-Service, and possibly Remote Code Execution...

SUSE CVE-2020-25767

An issue was discovered in HCC Embedded NicheStack IPv4 4.1. The dnccopyin routine for parsing DNS domain names does not check whether a domain name compression pointer is pointing within the bounds of the packet e.g., forward compression pointer jumps are allowed, which leads to an Out-of-bounds...

SUSE CVE-2020-25926

The DNS client in InterNiche NicheStack TCP/IP 4.0.1 is affected by: Insufficient entropy in the DNS transaction id. The impact is: DNS cache poisoning remote. The component is: dnsquerytype. The attack vector is: a specific DNS response packet...

SUSE CVE-2020-25928

The DNS feature in InterNiche NicheStack TCP/IP 4.0.1 is affected by: Buffer Overflow. The impact is: execute arbitrary code remote. The component is: DNS response processing functions: dnsupcall, getoffset, dncsetanswer. The attack vector is: a specific DNS response packet. The code does not che...

SUSE CVE-2020-25927

The DNS feature in InterNiche NicheStack TCP/IP 4.0.1 is affected by: Out-of-bounds Read. The impact is: a denial of service remote. The component is: DNS response processing in function: dnsupcall. The attack vector is: a specific DNS response packet. The code does not check whether the number o...

SUSE CVE-2020-27840

A flaw was found in samba. Spaces used in a string around a domain name DN, while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability...

SUSE CVE-2021-3448

A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ...

SUSE CVE-2021-3672

A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS Domain Name Servers can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as we...

SUSE CVE-2021-22931

Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames leading to Domain Hijacking and injection...

SUSE CVE-2021-23017

A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact...

SUSE CVE-2021-31228

An issue was discovered in HCC embedded InterNiche 4.0.1. This vulnerability allows the attacker to predict a DNS query's source port in order to send forged DNS response packets that will be accepted as valid answers to the DNS client's requests without sniffing the specific request. Data is...

SUSE CVE-2021-33195

Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection e.g., XSS that does not conform to the RFC1035 format...
