NVD Description

Note: Versions mentioned in the description apply only to the upstream opentelemetry-collector package and not the opentelemetry-collector package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

The "go bug" command writes to two files with predictable names in the system temporary directory (for example, "/tmp"). An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink.
