SCA: security update for go.opentelemetry.io/obi (GHSA-43g7-cwr8-q3jh)

high Tenable Cloud Security Plugin ID 442114

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From
 version 0.7.0 to before version 0.9.0, a remotely reachable integer overflow in OBI's memcached text
 protocol parser can crash the OBI process and cause denial of service. When parsing memcached storage
 commands such as set, add, replace, append, prepend, or cas, OBI accepts extremely large <bytes> values
 and adds the payload delimiter length without checking for overflow. A crafted request with <bytes> set to
 math.MaxInt or math.MaxInt-1 causes the computed payload length to wrap negative and triggers a runtime
 panic in LargeBufferReader.Peek. This issue has been patched in version 0.9.0. (CVE-2026-45686)

Solution

Update the go.opentelemetry.io/obi library and its related packages to version 0.9.0 or later.
