Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2018-19974 not yet assigned priority: Debian including 1 source packages (yara), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
In YARA 3.8.1, bytecode in a specially crafted compiled rule can read uninitialized data from VM scratch memory in libyara/exec.c. This can allow attackers to discover addresses in the real stack (not the YARA virtual stack).
