CVE-2016-6313 Open this link in a new tabHow to fix?
Upgrade Debian:12 libgcrypt20 to version 1.7.3-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgcrypt20 package and not the libgcrypt20 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
