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 ...

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: LDAP injection vulnerability in LDAPStoreHelper.java

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The LDAPStoreHelper implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying...

CVE-2026-12852

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit this by providing a specially crafted message to the MLS wire decoder. The decoder allocates an attacker-declared opaque length without first performing a bounds check. This can lead to excessive memory allocation,...

CVE-2026-13505

In Bouncy Castle for Java FIPS BC-FJA before bc-fips 1.0.2.7 1.0.X series, 2.0.2 2.0.X series and 2.1.3 2.1.X series, sensitive key material held by the AES and DESede engines, the SP 800-90A DRBGs, SymmetricSecretKey and the PBKD and scrypt parameter classes was zeroised on garbage collection by...

CVE-2024-14041

A flaw was found in Bouncy Castle for Java, affecting ML-KEM CRYSTALS-Kyber routines. Specifically, the Poly.toMsg, Poly.compressPoly, and PolyVec.compressPolyVec routines, which handle secret-derived polynomial coefficients, perform division by the modulus q. A remote attacker can exploit this...
