Affected: CleanStart: opentelemetry-collector-contrib

Multiple security vulnerabilities affect the opentelemetry-collector-contrib package. These issues are resolved in later releases. See references for individual vulnerability details.

OpenTelemetry eBPF Profiler is a production-scale agent for profiling applications across multiple programming languages. Starting in version 0.0.202527 and prior to version 0.0.202622, an unprivileged process can cause the profiler to open a nonregular mapping file, such as a FIFO, and block indefinitely, preventing further ELF analysis and causing a denial of service. Version 0.0.202622 contains a patch. No known workarounds are available.

Affected: Go: go.opentelemetry.io/ebpf-profiler

### 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

Fixed in https://github.com/open-telemetry/opentelemetry-ebpf-profiler/commit/234b685cab31c2cb2f79e966caeab168bcc489e4.

Fix is part of [v.0.0.202622](https://github.com/open-telemetry/opentelemetry-ebpf-profiler/releases/tag/v0.0.202622).
