Executive Summary

This vulnerability is a remotely-triggerable panic in the golang.org/x/text/secure/precis package. It occurs when the Nickname profile processes crafted input that causes an out-of-bounds slice error during transformation. Specifically, a 3-byte input crashes the system by violating the transform.Transformer contract due to missing bounds checks when writing an inserted ASCII space and unconditionally advancing the destination buffer index.
