A bug in the SmallVec::insert_many method caused it to allocate a buffer that was smaller than needed. It then wrote past the end of the buffer, causing a buffer overflow and memory corruption on the heap.
This bug was only triggered if the iterator passed to insert_many yielded more items than the lower bound returned from its size_hint method.
The flaw was corrected in smallvec 0.6.14 and 1.6.1, by ensuring that additional space is always reserved for each item inserted. The fix also simplified the implementation of insert_many to use less unsafe code, so it is easier to verify its correctness.
Thank you to Yechan Bae (@Qwaz) and the Rust group at Georgia Tech’s SSLab for finding and reporting this bug.
There was a logic bug where unauthenticated payloads could still cause a nonce
increment in snow's internal state. For an attacker with privileges to inject
packets into the channel over which the Noise session operates, this could
allow a denial-of-service attack which could prevent message delivery by
sending garbage data.
Note that this only affects those who are using the stateful TransportState,
not those using StatelessTransportState.
This has been patched in version 0.9.5, and all users are recommended to
update.
