PERTAIN_TOSolution

Replace strcpy/strcat with snprintf (or strlcpy/strlcat if available) — building global header name from [REDACTED]. Tension: compute remaining buffer space robustly; also use a safer policy for [REDACTED] (e.g., cap length). Outcome: Add overflow checks when computing allocation size.

PERTAIN_TOProblem

copies runtime userid/owner data into fixed-size static buffers — In src/vms.c, the VMS-specific getpwuid() replacement. Tension: using strcpy with no length checks. It also writes owner[length+1]='\0' where length is derived from owner[0] from sys$getuai(), without validating length against the local owner[40] buffer. Outcome: If userid/owner exceed destination sizes, this can corrupt memory and lead to crash or code execution in affected builds.

PERTAIN_TOReport

Unbounded strcpy in VMS getpwuid shim can overflow static buffers
