Detailsinfo

A vulnerability, which was classified as critical, was found in SuSE Linux Enterprise Server 15/up to 12 (Operating System). This affects an unknown part in the library /var/lib/nfs of the component nfs-utils Package. The manipulation with an unknown input leads to a privileges management vulnerability.
