fugit contains time tools for flor and the floraison group. The fugit "natural" parser, that turns "every wednesday at 5pm" into "0 17 * * 3", accepted any length of input and went on attempting to parse it, not returning promptly, as expected. The parse call could hold the thread with no end in sight. Fugit dependents that do not check (user) input length for plausibility are impacted. A fix was released in fugit 1.11.1.

    ### Impact The fugit "natural" parser, that turns "every wednesday at 5pm" into "0 17 * * 3", accepted any length of input and went on attempting to parse it, not returning promptly, as expected. The parse call could hold the thread with no end in sight. Fugit dependents that do not check (user) input length for plausability are impacted. ### Patches Problem was reported in #104 and the fix was released in [fugit 1.11.1](https://rubygems.org/gems/fugit/versions/1.11.1) ### Workarounds By making sure that `Fugit.parse(s)`, `Fugit.do_parse(s)`, `Fugit.parse_nat(s)`, `Fugit.do_parse_nat(s)`, `Fugit::Nat.parse(s)`, and `Fugit::Nat.do_parse(s)` are not fed strings too long. 1000 chars feels ok, while 10_000 chars makes it stall. In fewer words, making sure those fugit methods are not fed unvetted input strings. ### References gh-104
