Vulnerability Title
OpenTelemetry eBPF Instrumentation: Unsafe fastelf parsing allows malformed ELF to crash agent
Source: NVD (National Vulnerability Database)
Vulnerability Description
OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI's replacement ELF parser trusts section offsets, counts, and string offsets from the executable file. A crafted local ELF can make OBI dereference invalid section pointers or slice past string tables, causing the agent to panic while determining the process language. This issue has been patched in version 0.9.0.
