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 values that is quite easy to guess, this can lead to DNS cache poisoning.</p> <p>An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products.

A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The function used in uIP-Contiki-OS to decapsulate RPL extension headers does not check for unsafe integer conversion when parsing the values provided in a header, allowing an attacker to corrupt memory.CVE-2020-13985 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The function used in uIP-Contiki-OS to decapsulate RPL extension headers does not check the length value of an RPL extension header received, allowing an attacker to cause it to enter an infinite loop.CVE-2020-13986 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The function in open-iscsi, uIP-Contiki-OS, and uIP that parses incoming transport layer packets (TCP/UDP) does not check the length fields of packet headers against the data available in the packets. Given arbitrary lengths, an out-of-bounds memory read may be performed during the checksum computation.CVE-2020-13987 has been assigned to this vulnerability.
