NVD Description

Note: Versions mentioned in the description apply only to the upstream gnupg2 package and not the gnupg2 package as distributed by Ubuntu.

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.
