GHSA-GWM6-Q8CH-HCFR install -D: symlink race in directory creation allows arbitrary file overwrite

The -D path runs fs::createdirall on a pathname then later opens the destination via path-based File::create/fs::copy, neither anchored to a directory fd. Between the two, an attacker can replace a path component with a symlink, redirecting the write. Impact: an attacker with concurrent write...

GHSA-4X34-CHG5-MWJJ chmod: recursive mode returns exit code 0 even when some files fail (last-file-wins)

In Chmoder::chmod the recursive branch overwrites the running result instead of accumulating it, so the exit code reflects only the last file processed: if self.recursive r = self.walkdirwithcontextfile, true; // overwrites r else r = self.chmodfilefile.andr; PoC: GNU returns 1 when a file fails;...
