Details:
If the stem len is bigger than PATH_MAX, it results in a buffer over run:
455a456
> unsigned int stemlen_copy;
494,495c495,497
< strncpy (stem_str, stem, stemlen);
< stem_str[stemlen] = '\0';
---
> stemlen_copy = stemlen > sizeof(stem_str) ? sizeof(stem_str) :
stemlen;
> strncpy (stem_str, stem, stemlen_copy);
> stem_str[stemlen_copy] = '\0';
