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
.
