CVE-2016-1000339 [MEDIUM] CWE-310 CVE-2016-1000339: In the Bouncy Castle JCE Provider version 1.55 and earlier the primary engine class used for AES was In the Bouncy Castle JCE Provider version 1.55 and earlier the primary engine class used for AES was AESFastEngine. Due to the highly table driven approach used in the algorithm it turns out that if the data channel on the CPU can be monitored the lookup table accesses are sufficient to leak information on the AES key being used. There was also

CVE-2026-12860 [MEDIUM] CWE-347 CVE-2026-12860: In Bouncy Castle for Java before 1.85, RSA PKCS#1 verification skips last two hash bytes in NULL-omi In Bouncy Castle for Java before 1.85, RSA PKCS#1 verification skips last two hash bytes in NULL-omitted path. This issue also affects Bouncy Castle for Java LTS before 2.73.12.

CVE-2016-2427 [MEDIUM] CWE-200 CVE-2016-2427: The AES-GCM specification in RFC 5084, as used in Android 5.x and 6.x, recommends 12 octets for the The AES-GCM specification in RFC 5084, as used in Android 5.x and 6.x, recommends 12 octets for the aes-ICVlen parameter field, which might make it easier for attackers to defeat a cryptographic protection mechanism and discover an authentication key via a crafted application, aka internal bug 26234568. NOTE: The vendor disputes the existence of this p

CVE-2013-1624 [MEDIUM] CVE-2013-1624: The TLS implementation in the Bouncy Castle Java library before 1.48 and C# library before 1.8 does The TLS implementation in the Bouncy Castle Java library before 1.48 and C# library before 1.8 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of tim

CVE-2018-5382 [MEDIUM] CWE-327 CVE-2018-5382: The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compr The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS keystore. Bouncy Castle release 1.47 changes the BKS format to a format which uses a 160 bit HMAC instead. This applies to any BKS keystore generated prior to BC 1.47. For situations where people need to create the files for

CVE-2016-1000346 [LOW] CWE-320 CVE-2016-1000346: In the Bouncy Castle JCE Provider version 1.55 and earlier the other party DH public key is not full In the Bouncy Castle JCE Provider version 1.55 and earlier the other party DH public key is not fully validated. This can cause issues as invalid keys can be used to reveal details about the other party's private key where static Diffie-Hellman is in use. As of release 1.56 the key parameters are checked on agreement calculation.
