yabs geekbench_6 started with an executable stack. Should you worry ?

what do you think ?

So I quit running yabs on my servers due to this. However just got a new vps that I will be deleting the template and reinstalling so I gave yabs a run to see if this was still an issue ( for me ). and it is.

process 'root/2025-06-18T17_49_30+00_00/geekbench_6/geekbench_avx2' started with executable stack

further information: https://www.elastic.co/guide/en/security/8.18/process-started-with-executable-stack.html

The issue brought up on yabs github: https://github.com/masonr/yet-another-bench-script/issues/42

the summary from the devoloper masonr is:

Ultimately, it's up to the end user if they feel comfortable enough to run this code.
I may take a stab at adding an option for a tool such as sysbench to be used in place of geekbench, but for now it'll remain as is

I know yabs is extremely popular around here but am surprised that running a downloaded closed source binary as root which messes with the executable stack is not more discussed . And yes, on my github issue I mention that yabs could be run without the geekbench code.

edited - I wrongly thought it needed to be ran as root

    1. cron has superpowers making this exploit void
    2. dont care
    3. its just an idler anyway

    need to update the original post stating geekbench isnt open source. so it is a closed source binary running as root modifying the executable stack

    You should not run it as root anyway..

    true. It had been awhile since I ran it and wrongly thought it needed root. I am still concerned with and would like to learn more about a binary modifying the executable stack
