  • #Mythos finds a #curl vulnerability
    oots@infosec.exchangeO oots@infosec.exchange

    @das_robin @bagder
    Yes, #Firefox is probably a few orders of magnitude more complex than #curl and definitely much bigger.

    Still, the blog post explicitly mentions "In addition to fixing the 271 bugs identified by Claude Mythos Preview in the 150 release, we’ve shipped more of these fixes in 149.0.2, 150.0.1, and 150.0.2.", so >270 attributed to #Mythos *alone*.

    In terms of evidence to the contrary:
    Check out
    https://social.security.plumbing/@freddy/116549451049357174 / the blog post:
    https://hacks.mozilla.org/2026/05/behind-the-scenes-hardening-firefox/

    >270 vulnerabilities found by Mythos fixed in a single Firefox release.

    That's just one data point, but interestingly far off from yours.

    #RocketLang update:
    I implemented some additional library functions, namely:
    - `dynamic_type(x)`: returns the actual runtime type of the object. E.g., if the variable x is declared as `SomeProtocol` but you assign an instance of a structure implementing that protocol, it will give you the structure type.
    - `is_subtype(T1, T2)` tests if T1 is a subtype of T2, similar to Python's `issubclass()`
    - `os.scandir()` for getting the contents of a directory

    I also added a generic iterator that works with `ArrayList`s and array `Slice`s. All it needs is that the underlying container can be queried by `container[index]` and can be queried for its length.
    (I actually already had this implemented for ArrayLists, just made it more generic to make it work for Slices, too.)

    This actually required fixing a "bug" in checking whether a type implements a protocol. Implemented naively, that lead into an infinite recursion. (I was aware of that and had a FIXME in my code.) Now I accidentally triggered that and figured it was a good time to actually fix that.
