Improper Validation of Integrity Check Value in Bouncy Castle

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...

The vulnerability of the pseudorandom number generator in the Libgcrypt cryptography library, related to information disclosure, allows a hacker to predict the output data.

The vulnerability of the pseudorandom number generator in the Libgcrypt cryptography library is related to an error that causes the generation of a 160-bit random number from a standard random number generator. Exploiting this vulnerability allows a remote attacker to predict the output data...

ALPINE-CVE-2016-6313

The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits...
