Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the readBlock method of PGPAeadInputStream BcAEADUtil, mirrored in JceAEADUtil, which pre-reads the final 16 bytes but ignores the result and returns EOF without calling doFinal when the...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion in the force method of LazyEncodedSequence, which parses the deferred SEQUENCE with a fresh ASN1InputStream whose nesting-depth counter is reset rather than inherited from the parent parse, and never calls...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the toByteArray method of DefiniteLengthInputStream, which allocates new byteintremaining up front from the declared ASN.1 definite-length value before reading any content. An attacker can...
