7.5 highEPSS 0.3%

High (7.5) in opentelemetry ebpf instrumentation. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in go.opentelemetry.io/obi 0.9.0.

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the Postgres protocol parser assumes BIND message payloads contain a valid NUL-terminated portal name. A crafted empty or unterminated payload can make OBI slice beyond the end of the captured buffer and panic. This issue has been patched in version 0.9.0.
