Published Aug 12, 2025 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
Allocation of Resources Without Limits or Throttling vulnerability in Legion of the Bouncy Castle Inc. BC Java bcprov on All (API modules), Legion of the Bouncy Castle Inc. BC-FJA bc-fips on All allows Excessive Allocation. This vulnerability is associated with program files https://github.com/bcgit/bc-java/blob/main/core/src/main/java/org/bouncycastle/asn1/ASN1ObjectIdenti... https://github.com/bcgit/bc-java/blob/main/core/src/main/java/org/bouncycastle/asn1/ASN1ObjectIdentifier.Java .

This issue affects BC Java: from 1.0 through 1.77; BC-FJA: from 1.0.0 through 1.0.2.5, from 2.0.0 through 2.0.1.

Remediation

Vendor Workaround

Limiting the size of ASN.1 objects that can be loaded from "the wild", or putting in place some other validation for such objects, will mitigate the risk of an exploit by automatically putting a cap on the maximum size of an ASN.1 OBJECT IDENTIFIER.
