CVE-2021-29939 07:15
An issue was discovered in the stackvector crate through 2021-02-19 for
Rust. There is an out-of-bounds write in StackVec::extend if size_hint
provides certain anomalous data.
No fix released upstream yet:
https://github.com/Alexhuszagh/rust-stackvector/issues/2
Out of bounds write sounds like it could have dangerous consequences,
not sure how likely is "size_hint provides certain anomalous data"
though.

Thanks for the report.
Commit 015cd2e86e779907085d356c69b6091dc8ac1788 updating to 1.1.1 should
fix the security issue; as upstream said. So, closing.
All the best,
simon
