CVE-2020-25928 (GCVE-0-2020-25928)

Vulnerability from cvelistv5 – Published: 2021-08-18 18:41 – Updated: 2024-08-04 15:49
VLAI
Summary
The DNS feature in InterNiche NicheStack TCP/IP 4.0.1 is affected by: Buffer Overflow. The impact is: execute arbitrary code (remote). The component is: DNS response processing functions: dns_upcall(), getoffset(), dnc_set_answer(). The attack vector is: a specific DNS response packet. The code does not check the "response data length" field of individual DNS answers, which may cause out-of-bounds read/write operations, leading to Information leak, Denial-or-Service, or Remote Code Execution, depending on the context.
