Patch Tuesday overshadowed by Microsoft Exchange attacks Microsoft’s March Patch Tuesday update drops amid ongoing fall-out from widespread Exchange attacks Share this item with your network: By Published: 10 Mar 2021 11:40 Microsoft has patched a total of 89 common vulnerabilities and exposures (CVEs) in its latest Patch Tuesday update, which dropped on 9 March, including 14 bugs rated as critical – but the latest round of updates is overshadowed by the developing crisis around four CVEs disclosed last week in an out-of-band patch for Microsoft Exchange Server. The ongoing situation has seen a slew of emergency directives from national security agencies around the world, amid reports that more than 100,000 organisations may have been compromised. According to telemetry gathered by Palo Alto Networks’ Unit 42 team, the number of vulnerable servers totals 33,000 in the US, 21,000 in Germany, 7,900 in the UK, 5,100 in France and 4,600 in Italy.
