bouncycastle: BC-JAVA: GOSTCTR implementation unable to process more than 255 blocks correctly

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The GOSTCTR implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the G3413CTRBlockCiphe...

bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...

bouncycastle: BC-JAVA: private key leakage via non-constant time comparisons

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA core. A covert timing channel vulnerability, caused by non-constant time comparisons, risks the leakage of private keys in the FrodoKEM implementation. An unauthenticated, remote attacker can potentially exploit this timing discrepancy ...

GHSA-574F-3G2M-X479 Bouncy Castle for Java GOST 28147 CTR mode reuses keystream after 255 blocks

The GOST 28147-2015 CTR mode implementation G3413CTRBlockCipher in the Legion of the Bouncy Castle BC-JAVA bcprov core module only increments the final byte of the counter, so the counter wraps after 255 blocks and the keystream is reused. Reusing CTR keystream allows an attacker who can observe...
