| Doc Text: |
A flaw was found in Bouncy Castle for Java, a cryptographic library. An attacker can exploit this vulnerability by manipulating rfc822Name and URI fields within X.509 certificates using a trailing dot. This bypasses Name Constraints, potentially leading to spoofing or unauthorized access. Such an exploit impacts the integrity and confidentiality of communications.
