Description
A memory disclosure vulnerability exists in libcoap's OSCORE configuration parser in libcoap before release-4.3.5-patches. An out-of-bounds read may occur when parsing certain configuration values, allowing an attacker to infer or read memory beyond string boundaries in the .rodata section. This could potentially lead to information disclosure or denial of service.

Executive Summary

This vulnerability is a memory disclosure issue in libcoap's OSCORE configuration parser before version 4.3.5-patches. It involves an out-of-bounds read when parsing certain configuration values, which allows an attacker to read memory beyond the intended string boundaries in the read-only data section (.rodata).

Impact Analysis

The vulnerability can lead to information disclosure by allowing attackers to infer or read sensitive memory contents beyond intended boundaries. It may also cause denial of service by triggering unexpected behavior in the parser.
