An exploitable command execution vulnerability exists in the ASN1 certificate writing functionality of Openweave-core version 4.0.2. A specially crafted weave certificate can trigger a heap-based buffer overflow, resulting in code execution. An attacker can craft a weave certificate to trigger this vulnerability.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
