Description
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.

| Decided by | Medium or Low severity, no CISA or VulnCheck KEV listing, no PoC clearing the evidence bar, no CISA verdict, no Oracle advisory |
|---|---|
| Finding | This CVE is MEDIUM severity, is not listed in CISA KEV or VulnCheck KEV, has no public exploit or PoC in any indexed source, carries no CISA Vulnrichment finding of a demonstrated exploit, and is not part of an Oracle Critical Patch Update. None of the signals that would put it in front of an engineer is present, and the volume of CVEs below that bar is too great to take one at a time, so no rule is written for it. This is a decision about what we act on, not a finding that the CVE is harmless — a patch may well be derivable, and a low-severity defect can still be one link in a longer chain. |
