VeraCrypt security audit reveals many flaws, some already patched [Zeljka Zorz/Helpnet Security]
VeraCrypt, the free, open source disk encryption software based on TrueCrypt, has been audited by experts from cybersecurity company Quarkslab.
The researchers found 8 critical, 3 medium, and 15 low-severity vulnerabilities, and some of them have already been addressed in version 1.19 of the software, which was released on the same day as the audit report.
The code auditing effort analyzed VeraCrypt 1.18 and its bootloaders.
"A first step consisted in verifying that the problems and vulnerabilities identified by iSec and NCC Group in TrueCrypt 7.1a for the Open Crypto Audit Project had been taken into account and fixed," the Quarkslab researchers involved in the effort explained.
"Then, the remaining study was to identify potential security problems in the code specific to VeraCrypt. Contrary to other TrueCrypt forks, the goal of VeraCrypt is not only to fix the public vulnerabilities of TrueCrypt, but also to bring new features to the software."
A short overview of the issues found (fixed and still not fixed) can be found here. The audit report, with mitigations for still unpatched vulnerabilities, can be downloaded from here.
Are any Soylentils using Veracrypt and/or other forks of Trucrypt?

These include the AES implementation, which is still susceptible to cache-timing attacks.
Mitigation: replace AES with Camellia
So in order to carry out this attack you need to have an attacker's hostile software running with root privs, or close to it, on the CPU doing the disk encryption. Mitigation: Not a real attack, nothing to mitigate.
(Also, how do you know the Camellia implementation is any better?).

Your right, Camellia has the potential to be worse
Be like us, be different, be a nihilist!!!

I missed that phrase : "NCC Group’s report only focuses on AES. We did not check if other implementations are
susceptible to such attacks" when I first read the report, I apologize
