Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-2690 low priority: Ubuntu including 1 source packages (libguestfs), 16 status rows across 16 suites (hardy, lucid, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): not-affected 9, DNE 5, ignored 1, released 1.
virt-edit in libguestfs before 1.18.0 does not preserve the permissions from the original file and saves the new file with world-readable permissions when editing, which might allow local guest users to obtain sensitive information.
