CVE-2020-24338 [CRITICAL] CWE-787 CVE-2020-24338: An issue was discovered in picoTCP through 1.7.0. The DNS domain name record decompression functiona An issue was discovered in picoTCP through 1.7.0. The DNS domain name record decompression functionality in pico_dns_decompress_name() in pico_dns_common.c does not validate the compression pointer offset values with respect to the actual data present in a DNS response packet, causing out-of-bounds writes that lead to Denial-of-Service and Remote

CVE-2020-17441 [CRITICAL] CWE-125 CVE-2020-17441: An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate whether the IPv6 payload length field is equal to the actual size of the payload, which leads to an Out-of-Bounds read during the ICMPv6 checksum calculation, resulting in either Denial-of-Service or Information Disclosure. This affects pico_ipv6_e

CVE-2020-24341 [CRITICAL] CWE-125 CVE-2020-24341: An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing funct An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing function in pico_tcp.c does not validate the length of incoming TCP packets, which leads to an out-of-bounds read when assembling received packets into a data segment, eventually causing Denial-of-Service or an information leak.

CVE-2017-1000210 [CRITICAL] CWE-119 CVE-2017-1000210: picoTCP (versions 1.7.0 - 1.5.0) is vulnerable to stack buffer overflow resulting in code execution picoTCP (versions 1.7.0 - 1.5.0) is vulnerable to stack buffer overflow resulting in code execution or denial of service attack

CVE-2021-33304 [CRITICAL] CWE-415 CVE-2021-33304: Double Free vulnerability in virtualsquare picoTCP v1.7.0 and picoTCP-NG v2.1 in modules/pico_fragme Double Free vulnerability in virtualsquare picoTCP v1.7.0 and picoTCP-NG v2.1 in modules/pico_fragments.c in function pico_fragments_reassemble, allows attackers to execute arbitrary code.

CVE-2020-17445 [HIGH] CWE-125 CVE-2020-17445: An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 destination options does An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 destination options does not check for a valid length of the destination options header. This results in an Out-of-Bounds Read, and, depending on the memory protection mechanism, this may result in Denial-of-Service in pico_ipv6_process_destopt() in pico_ipv6.c.

CVE-2020-24340 [HIGH] CWE-125 CVE-2020-24340: An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The code that processes DNS respons An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The code that processes DNS responses in pico_mdns_handle_data_as_answers_generic() in pico_mdns.c does not check whether the number of answers/responses specified in a DNS packet header corresponds to the response data available in the packet, leading to an out-of-bounds read, invalid p

CVE-2020-17443 [HIGH] CWE-190 CVE-2020-17443: An issue was discovered in picoTCP 1.7.0. The code for creating an ICMPv6 echo replies doesn't check An issue was discovered in picoTCP 1.7.0. The code for creating an ICMPv6 echo replies doesn't check whether the ICMPv6 echo request packet's size is shorter than 8 bytes. If the size of the incoming ICMPv6 request packet is shorter than this, the operation that calculates the size of the ICMPv6 echo replies has an integer wrap around, leading to memo

CVE-2020-17442 [HIGH] CWE-190 CVE-2020-17442: An issue was discovered in picoTCP 1.7.0. The code for parsing the hop-by-hop IPv6 extension headers An issue was discovered in picoTCP 1.7.0. The code for parsing the hop-by-hop IPv6 extension headers does not validate the bounds of the extension header length value, which may result in Integer Wraparound. Therefore, a crafted extension header length value may cause Denial-of-Service because it affects the loop in which the extension headers are par

CVE-2020-17444 [HIGH] CWE-20 CVE-2020-17444: An issue was discovered in picoTCP 1.7.0. The routine for processing the next header field (and dedu An issue was discovered in picoTCP 1.7.0. The routine for processing the next header field (and deducing whether the IPv6 extension headers are valid) doesn't check whether the header extension length field would overflow. Therefore, if it wraps around to zero, iterating through the extension headers will not increment the current data pointer. This le

CVE-2020-24339 [HIGH] CWE-125 CVE-2020-24339: An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The DNS domain name record decompre An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The DNS domain name record decompression functionality in pico_dns_decompress_name() in pico_dns_common.c does not validate the compression pointer offset values with respect to the actual data present in a DNS response packet, causing out-of-bounds reads that lead to Denial-of-Service.

CVE-2023-30463 [HIGH] CWE-190 CVE-2023-30463: Altran picoTCP through 1.7.0 allows memory corruption (and subsequent denial of service) because of Altran picoTCP through 1.7.0 allows memory corruption (and subsequent denial of service) because of an integer overflow in pico_ipv6_alloc when processing large ICMPv6 packets. This affects installations with Ethernet support in which a packet size greater than 65495 may occur.

CVE-2020-24337 [HIGH] CWE-835 CVE-2020-24337: An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. When an unsupported TCP option with An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. When an unsupported TCP option with zero length is provided in an incoming TCP packet, it is possible to cause a Denial-of-Service by achieving an infinite loop in the code that parses TCP options, aka tcp_parse_options() in pico_tcp.c.
