Overview
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the toByteArray() method of DefiniteLengthInputStream, which allocates new byte[(int)_remaining] up front from the declared ASN.1 definite-length value before reading any content. An attacker can drive the JVM to OutOfMemoryError with a small input by supplying an ASN.1 structure whose definite-length header declares a near-heap-sized length that the content never satisfies. This requires the application to parse attacker-supplied ASN.1 or DER input, such as certificates, CMS structures, or keys, through Bouncy Castle.
