      <title>RUSTSEC-2020-0142 — Send bound needed on T (for Send impl of `Bucket2`)</title>
      <link>https://cve.radiocsirt.org/vuln/rustsec-2020-0142</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; crates.io: syncpool&lt;/p&gt;
&lt;p&gt;Affected versions of this crate unconditionally implements `Send` for `Bucket2`. This allows sending non-Send types to other threads.&lt;/p&gt;
&lt;p&gt;This can lead to data races when non Send types like `Cell&amp;lt;T&amp;gt;` or `Rc&amp;lt;T&amp;gt;` are contained inside `Bucket2` and sent across thread boundaries. The data races can potentially lead to memory corruption (as demonstrated in the PoC from the original report issue).&lt;/p&gt;
&lt;p&gt;The flaw was corrected in commit 15b2828 by adding a `T: Send` bound to the `Send` impl of `Bucket2&amp;lt;T&amp;gt;`.&lt;/p&gt;</description>
