| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2020-24335 | An issue was discovered in uIP through 1.0, as used in Contiki and Contiki-NG. Domain name parsing lacks bounds checks, allowing an attacker to corrupt memory with crafted DNS packets. | [email protected] | 7.5 | 2.09% | 2021-02-02 | 2024-11-21 |
| 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 resolv.c. | [email protected] | 8.2 | 0.64% | 2020-12-11 | 2024-11-21 |
| CVE-2020-17440 | An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that parses incoming DNS packets does not validate that domain names present in the DNS responses have '\0' termination. This results in errors when calculating the offset of the pointer that jumps over domain name bytes in DNS response packets when a name lacks this termination, and eventually leads to dereferencing the pointer at an invalid/arbitrary address, within newdata() and parse_name() in resolv.c. | [email protected] | 7.5 | 0.58% | 2020-12-11 | 2024-11-21 |
| CVE-2020-17439 | An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that parses incoming DNS packets does not validate that the incoming DNS replies match outgoing DNS queries in newdata() in resolv.c. Also, arbitrary DNS replies are parsed if there was any outgoing DNS query with a transaction ID that matches the transaction ID of an incoming reply. Provided that the default DNS cache is quite small (only four records) and that the transaction ID has a very limited set of va | [email protected] | 8.3 | 0.29% | 2020-12-11 | 2024-11-21 |
| CVE-2020-17438 | An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that reassembles fragmented packets fails to properly validate the total length of an incoming packet specified in its IP header, as well as the fragmentation offset value specified in the IP header. By crafting a packet with specific values of the IP header length and the fragmentation offset, attackers can write into the .bss section of the program (past the statically allocated buffer that is used for stor | [email protected] | 9.8 | 0.82% | 2020-12-11 | 2024-11-21 |
| CVE-2020-17437 | An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. When the Urgent flag is set in a TCP packet, and the stack is configured to ignore the urgent data, the stack attempts to use the value of the Urgent pointer bytes to separate the Urgent data from the normal data, by calculating the offset at which the normal data should be present in the global buffer. However, the length of this offset is not checked; therefore, for large values of the Urgent pointer bytes, the data | [email protected] | 8.2 | 0.34% | 2020-12-11 | 2024-11-21 |
| CVE-2020-13987 | An issue was discovered in Contiki through 3.0. An Out-of-Bounds Read vulnerability exists in the uIP TCP/IP Stack component when calculating the checksums for IP packets in upper_layer_chksum in net/ipv4/uip.c. | [email protected] | 7.5 | 0.14% | 2020-12-11 | 2024-11-21 |
