3. Description:

 

The libgcrypt library provides general-purpose implementations of various

cryptographic algorithms.

 

Security Fix(es):

 

* A design flaw was found in the libgcrypt PRNG (Pseudo-Random Number

Generator). An attacker able to obtain the first 580 bytes of the PRNG

output could predict the following 20 bytes. (CVE-2016-6313)

 

Red Hat would like to thank Felix Dörre and Vladimir Klebanov for reporting

this issue.
