CVE-2019-12904 Open this link in a new tabHow to fix?
Upgrade Alpine:3.9 libgcrypt to version 1.8.4-r1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgcrypt package and not the libgcrypt package as distributed by Alpine.
See How to fix? for Alpine:3.9 relevant fixed versions and status.
In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the vendor's position is that the issue report cannot be validated because there is no description of an attack
