Following an undisclosed issue that resulted in a month-long delay in releasing security patches, Microsoft’s Patch Tuesday is back.

The company released 18 security bulletins this week that address vulnerabilities in server and desktop software, according to the Security Bulletin summary.

Of the patches released, one is aimed at addressing a Windows SMB memory corruption flaw that affects all versions of Windows in different ways. Discovered by Laurent Gaffié, who was not credited in the bulletin, the vulnerability’s proof-of-concept code was released days before March’s scheduled Patch Tuesday.

By leveraging the flaw, a remote attacker could crash the compromised machine, according to a February advisory by Carnegie Mellon University.

In total, the company addressed nine critical vulnerabilities. Microsoft has not explained why its February edition of Patch Tuesday was delayed.
