Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-12424 not yet assigned priority: Debian including 1 source packages (shadow), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.
