Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2021-36386 unimportant priority: Debian including 1 source packages (fetchmail), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user.
