CyberRota Analysis

AI-Generated

The OpenTelemetry-Go implementation is vulnerable due to an unsynchronized `extraBaggageItems` map in the OpenTracing bridge, which can lead to a fatal runtime error when accessed concurrently. This vulnerability may result in a denial of service, causing the application to terminate unexpectedly. Organizations utilizing versions 0.11.0 through 1.44.0 should prioritize upgrading to version 1.45.0 to mitigate this risk.

Original NVD Description

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 0.11.0 through 1.44.0, the OpenTracing bridge's bridgeSpan contains an unsynchronized extraBaggageItems map which can cause a panic. Because Go maps are not safe for concurrent read/write access, concurrent SetBaggageItem and correlation.MapFromContext calls on the same hooked bridgeSpan can trigger a fatal runtime error—such as concurrent map read and map write or concurrent map iteration and map write—terminating the process and causing denial of service. This issue is fixed in version 1.45.0.
