CVE-2019-12904 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgcrypt11 package and not the libgcrypt11 package as distributed by Ubuntu.
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
