opentelemetry-ebpf-profiler: Unprivileged process can trigger a denial of service on the ebpf-profiler agent
Quick fix
GHSA-f2r5-5m7w-p5cx — go.opentelemetry.io/ebpf-profiler: upgrade to the fixed version with the command below.
go get go.opentelemetry.io/ebpf-profiler@v0.0.202622Details
### Summary
An unprivileged process can easily trigger the `processPIDEvents` goroutine to be blocked indefinitely, preventing the goroutine from analyzing any new ELF file. The goroutine stays blocked in the `openat2` syscall forever and the profiler can no longer work properly, it is a denial of service.
### Impact
The impact is limited to denial-of-service on the ebpf-profiler agent: - There has to be a malicious workload albeit unprivileged. - No exfiltration of data. No loss of data.
### Fix
