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-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...

CVE-2026-13505

CVE-2026-13505 concerns Bouncy Castle for Java FIPS (BC-FJA). The issue: sensitive key material held by AES/DESede engines, SP 800-90A DRBGs, SymmetricSecretKey, and PBKD/scrypt parameter classes was zeroised on garbage collection via Object.finalize. Finalization is non-deterministic and runs on...

CVE-2026-13505 Zeroisation of sensitive key material on garbage collection relies on finalization

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-2026-8798

CVE-2026-8798 affects Bouncy Castle for Java FIPS (BC-FJA) prior to bc-fips 2.1.3. The native entropy source on Intel platforms looped unbounded when RDSEED/RDRAND failed, risking a thread hang and potential denial of service as any operation using the native entropy source could stall. The fixes...

CVE-2026-8798 Native entropy source retries the CPU entropy instructions without limit

In Bouncy Castle for Java FIPS BC-FJA before bc-fips 2.1.3, the native entropy source used on Intel platforms retried the CPU entropy instructions without any bound. RDSEED and RDRAND report failure through their carry flag, and the JNI seeding routine spun re-issuing the instruction for as long ...
