The local composite operator $A_{\mu}^{2}$ is analysed within the algebraic
renormalization in Yang-Mills theories in linear covariant gauges. We establish
that it is multiplicatively renormalizable to all orders of perturbation
theory. Its anomalous dimension is computed to two-loops in the MSbar scheme.
