CVE-2017-7526 (opens in a new tab)How to fix?
There is no fixed version for Centos:6 libgcrypt.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgcrypt package and not the libgcrypt package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.
