Description ThisIsXenu 2021-06-09 23:16:51 UTC 
Description of problem:
Chromium should be built with control flow integrity (CFI) support, which helps prevent attackers from modifying the program's control flow. According to the build log for the latest chromium build:
https://kojipkgs.fedoraproject.org//packages/chromium/91.0.4472.77/1.fc34/data/logs/x86_64/build.log

the option "cfi=false" is used, but it should be "cfi=true". Note that this does mean that clang will need to be used to compile chromium.

I do not plan to use clang to build Chromium at this time. If that changes (or if CFI support is added to GCC), I will revisit this.
