Invalid UTF-8 Handling Leads to Infinite Loop in Go

Executive Summary

This vulnerability occurs when a norm.Iter processes input with invalid UTF-8 bytes, causing it to enter an infinite loop. This can lead to denial of service by consuming excessive CPU resources.

Detection Guidance

This vulnerability affects the golang.org/x/text/unicode/norm package before v0.39.0. To detect it, check your Go module dependencies for versions of this package below v0.39.0 using commands like 'go list -m all' or 'go mod graph'. Update to v0.39.0 or later to mitigate the issue.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards. It involves an infinite loop in Go's unicode/norm package when processing invalid UTF-8 bytes, which is a denial-of-service risk but does not inherently violate data protection or privacy requirements.
