Summary

Forge (node-forge) by digitalbazaar before 1.4.1 is affected. Its asn1.fromDer function decodes ASN.1 data inside BIT STRING values without consistently applying the maxDepth limit, and retains copies at each nesting level (CWE-674). An unauthenticated remote attacker sends crafted DER with nested BIT STRINGs to exhaust CPU and memory. A public exploit is linked in the references.

Description from the CNA

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the affected implementation used asn1.fromDer(), BIT STRING decoding, maxDepth to process the relevant input or security decision. node-forge decoded ASN.1 stored inside BIT STRING values without consistently applying the configured maxDepth limit and recursively retained copies at each nesting level. Crafted DER containing nested BIT STRINGs could cause excessive recursion, CPU use, and quadratic memory consumption during asn1.fromDer(). This issue is fixed in version 1.4.1.
