CVE-2021-38190: Out of bounds write in nalgebra
The Deserialize implementation for VecStorage did not maintain the invariant that the number of elements must equal nrows * ncols. Deserialization of specially crafted inputs could allow memory access beyond allocation of the vector.
This flaw was introduced in v0.11.0 (086e6e) due to the addition of an automatically derived implementation of Deserialize for MatrixVec. MatrixVec was later renamed to VecStorage in v0.16.13 (0f66403) and continued to use the automatically derived implementation of Deserialize.
