Vulnerability Title
Bouncy Castle BKS-V1 keystore files vulnerable to trivial hash collisions
Vulnerability Description
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 legacy reasons a specific keystore type "BKS-V1" was introduced in 1.49. It should be noted that the use of "BKS-V1" is discouraged by the library authors and should only be used where it is otherwise safe to do so, as in where the use of a 16 bit checksum for the file integrity check is not going to cause a security issue in itself.

Bouncy Castle BKS-V1 加密问题漏洞
Vulnerability Description
Bouncy Castle BC是Bouncy Castle组织的一个用于C＃和Java应用程序的加密库。 Bouncy Castle BKS-V1中存在加密问题漏洞，该漏洞源于Bouncy Castle BKS-V1文件所使用HMAC的长度仅为16位。攻击者可利用该漏洞绕过BKS完整性检测。
