Microsoft has released patches for 129 vulnerabilities as part of its June Patch Tuesday updates - the highest number of CVEs ever released by Microsoft in a single month.
Microsoft's June Patch Tuesday volume beats out the update from May, where it released fixes for 111 security flaws, including 16 critical bugs and 96 that are rated important.
Satnam Narang, staff research engineer at Tenable, told Threatpost that a trio of fixes stuck out in the Patch Tuesday updates, for flaws in Microsoft Server Message Block.
Two of these flaws exist in Microsoft Server Message Block 3.1.1.
The update also addressed a Windows critical RCE flaw that exists when Microsoft Windows fails to properly handle cabinet files.
