There is no fixed version for Centos:7 bind-pkcs11-libs.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bind-pkcs11-libs package and not the bind-pkcs11-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
