This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs.</p> <p>### Details</p> <p>An ASN.1 Denial of Service (Dos) vulnerability exists in the node-forge `asn1.fromDer` function within `forge/lib/asn1.js`. The ASN.1 DER parser implementation (`_fromDer`) recurses for every constructed ASN.1 value (SEQUENCE, SET, etc.) and lacks a guard limiting recursion depth. An attacker can craft a small DER blob containing a very large nesting depth of constructed TLVs which causes the Node.js V8 engine to exhaust its call stack and throw `RangeError: Maximum call stack size exceeded`, crashing or incapacitating the process handling the parse. This is a remote, low-cost Denial-of-Service against applications that parse untrusted ASN.1 objects.</p> <p>### Impact</p> <p>This vulnerability enables an unauthenticated attacker to reliably crash a server or client using node-forge for TLS connections or certificate parsing.</p> <p>This vulnerability impacts the ans1.fromDer function in `node-forge` before patched version `1.3.2`.</p> <p>Any downstream application using this component is impacted. These components may be leveraged by downstream applications in ways that enable full compromise of availability.</p> <p><strong>Affected:</strong> npm: node-forge</p> <p>### Summary</p> <p>An Uncontrolled Recursion (CWE-674) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing.
