| CVE-2020-12140 | 1 Contiki-ng | 1 Contiki-ng | 2021-12-09 | 8.3 HIGH | 8.8 HIGH |
| A buffer overflow in os/net/mac/ble/ble-l2cap.c in the BLE stack in Contiki-NG 4.4 and earlier allows an attacker to execute arbitrary code via malicious L2CAP frames. | |||||
| CVE-2019-9183 | 2 Contiki-ng, Contiki-os | 2 Contiki-ng, Contiki | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Contiki-NG through 4.3 and Contiki through 3.0. A buffer overflow is present due to an integer underflow during 6LoWPAN fragment processing in the face of truncated fragments in os/net/ipv6/sicslowpan.c. This results in accesses of unmapped memory, crashing the application. An attacker can cause a denial-of-service via a crafted 6LoWPAN frame. | |||||
| CVE-2021-21257 | 1 Contiki-ng | 1 Contiki-ng | 2021-06-24 | 5.0 MEDIUM | 7.5 HIGH |
| Contiki-NG is an open-source, cross-platform operating system for internet of things devices. The RPL-Classic and RPL-Lite implementations in the Contiki-NG operating system versions prior to 4.6 do not validate the address pointer in the RPL source routing header This makes it possible for an attacker to cause out-of-bounds writes with packets injected into the network stack. Specifically, the problem lies in the rpl_ext_header_srh_update function in the two rpl-ext-header.c modules for RPL-Classic and RPL-Lite respectively. The addr_ptr variable is calculated using an unvalidated CMPR field value from the source routing header. An out-of-bounds write can be triggered on line 151 in os/net/routing/rpl-lite/rpl-ext-header.c and line 261 in os/net/routing/rpl-classic/rpl-ext-header.c, which contain the following memcpy call with addr_ptr as destination. The problem has been patched in Contiki-NG 4.6. Users can apply a patch out-of-band as a workaround. | |||||
| CVE-2021-21279 | 1 Contiki-ng | 1 Contiki-ng | 2021-06-22 | 7.8 HIGH | 7.5 HIGH |
| Contiki-NG is an open-source, cross-platform operating system for internet of things devices. In verions prior to 4.6, an attacker can perform a denial-of-service attack by triggering an infinite loop in the processing of IPv6 neighbor solicitation (NS) messages. This type of attack can effectively shut down the operation of the system because of the cooperative scheduling used for the main parts of Contiki-NG and its communication stack. The problem has been patched in Contiki-NG 4.6. Users can apply the patch for this vulnerability out-of-band as a workaround. | |||||
| CVE-2020-24335 | 3 Contiki-ng, Contiki-os, Uip Project | 3 Contiki-ng, Contiki, Uip | 2021-02-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2020-13988 | 1 Contiki-ng | 1 Contiki-ng | 2020-12-16 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Contiki through 3.0. An Integer Overflow exists in the uIP TCP/IP Stack component when parsing TCP MSS options of IPv4 network packets in uip_process in net/ipv4/uip.c. | |||||
| CVE-2020-24334 | 3 Contiki-ng, Contiki-os, Uip Project | 3 Contiki-ng, Contiki, Uip | 2020-12-15 | 6.4 MEDIUM | 8.2 HIGH |
| 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. | |||||
| CVE-2018-16663 | 1 Contiki-ng | 1 Contiki-ng. | 2020-08-24 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in Contiki-NG through 4.1. There is a stack-based buffer overflow in parse_relations in os/storage/antelope/aql-parser.c while parsing AQL (storage of relations). | |||||
| CVE-2018-16666 | 1 Contiki-ng | 1 Contiki-ng. | 2020-08-24 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in Contiki-NG through 4.1. There is a stack-based buffer overflow in next_string in os/storage/antelope/aql-lexer.c while parsing AQL (parsing next string). | |||||
| CVE-2018-16667 | 1 Contiki-ng | 1 Contiki-ng. | 2019-10-03 | 4.4 MEDIUM | 7.0 HIGH |
| An issue was discovered in Contiki-NG through 4.1. There is a buffer over-read in lookup in os/storage/antelope/lvm.c while parsing AQL (lvm_register_variable, lvm_set_variable_value, create_intersection, create_union). | |||||
| CVE-2018-16664 | 1 Contiki-ng | 1 Contiki-ng. | 2018-10-26 | 4.4 MEDIUM | 7.0 HIGH |
| An issue was discovered in Contiki-NG through 4.1. There is a buffer overflow in lvm_set_type in os/storage/antelope/lvm.c while parsing AQL (lvm_set_op, lvm_set_relation, lvm_set_operand). | |||||
