org.bouncycastle/bc-java: org.bouncycastle/bcpg-fips: Bouncy Castle for Java: Data integrity compromise due to silently ignored OpenPGP inline-signature policy failures
In Bouncy Castle for Java before 1.85, OpenPGP inline-signature policy failures silently ignored. This issue also affects Bouncy Castle for Java FIPS (BC-FJA) before bcpg-fips 2.0.13.
A flaw was found in Bouncy Castle for Java and Bouncy Castle for Java FIPS (BC-FJA). This vulnerability allows an attacker to bypass OpenPGP inline-signature policy failures, which are silently ignored by the software. This silent disregard of policy failures can lead to a compromise of data integrity, as users may mistakenly believe that signature policies are being enforced when they are not. This could result in the acceptance of maliciou
