Summary

A resource exhaustion flaw exists in the DERDecoder class within wildfly-elytron-asn1. A remote attacker can send a specially crafted DER payload, causing excessive memory allocation based on an inflated length value without proper validation, leading to JVM memory exhaustion.

Risk Assessment

This can result in a remote Denial of Service (DoS) for services that process untrusted DER/ASN.1 input, including SASL authentication mechanisms and X.500 certificate principal parsing paths.

Recommendation

Update wildfly-elytron-asn1 to a version containing the fix. Until patched, consider limiting processing of untrusted DER/ASN.1 input and monitor JVM memory usage.

Original NVD description (English source)

A flaw was found in the DERDecoder class within wildfly-elytron-asn1. A remote attacker can exploit this resource exhaustion vulnerability by sending a specially crafted DER (Distinguished Encoding Rules) payload. The decoder attempts to allocate excessive memory based on an inflated length value without proper validation, leading to Java Virtual Machine (JVM) memory exhaustion. This results in a remote Denial of Service (DoS) for services that process untrusted DER/ASN.1 input, including SASL (Simple Authentication and Security Layer) authentication mechanisms and X.500 certificate principal parsing paths.
