CVE-2020-24341 (GCVE-0-2020-24341)
Vulnerability from nvd – Published: 2020-12-11 22:55 – Updated: 2024-08-04 15:12
VLAI
Summary
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.
Severity
No CVSS data available.

CVE-2020-24340 (GCVE-0-2020-24340)
Vulnerability from nvd – Published: 2020-12-11 22:54 – Updated: 2024-08-04 15:12
VLAI
Summary
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 pointer dereference, and Denial-of-Service.

No CVSS data available.

CVE-2020-24337 (GCVE-0-2020-24337)
Vulnerability from nvd – Published: 2020-12-11 22:44 – Updated: 2024-08-04 15:12
VLAI
Summary
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.
Severity
No CVSS data available.

CVE-2020-24341 (GCVE-0-2020-24341)
Vulnerability from cvelistv5 – Published: 2020-12-11 22:55 – Updated: 2024-08-04 15:12
VLAI
Summary
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.
Severity
No CVSS data available.

Summary
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 pointer dereference, and Denial-of-Service.

No CVSS data available.

CVE-2020-24337 (GCVE-0-2020-24337)

Summary
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.
