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...

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...
