Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2015-20109 medium priority: Ubuntu including 2 source packages (eglibc, glibc), 20 status rows across 10 suites (bionic, focal, jammy, kinetic, lunar, mantic, noble, trusty, upstream, xenial): DNE 8, not-affected 8, released 2, ignored 1, needs-triage 1.
end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue.
