Source: pandas
Version: 0.23.3+dfsg-2
Severity: important
Control: tags -1 fixed-upstream patch

np.array @ Series actually calculates Series @ np.array, which is an error for nonsquare matrices and a *wrong answer* for square matrices.

Fixed upstream by https://github.com/pandas-dev/pandas/pull/21578/commits/95d66f0e17c12a1ad661ad68c4fb49eadcf4b578
