There is no fixed version for Centos:6 nss.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nss package and not the nss package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
