Security Vulnerabilities

may_queue: may_queue's Queue lacks Send/Sync bound for its Send/Sync trait.

RUSTSEC-2020-0111

Affected versions of may_queue implements Send/Sync for its Queue type without restricting it to Sendable types and Syncable types.

This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.

smallvec: Buffer overflow in SmallVec::insert_many

RUSTSEC-2021-0003

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.
