2 of the CVEs were rated as being Critical, while 1 was deemed to be just Important.

  • Microsoft Outlook Security 

One of the CVEs covered and fixed in the June 2020 Patch Tuesday updates involve a Microsoft Outlook Security Vulnerability. If exploited, CVE-2020-1229 could allow attackers to automatically load remote images.

Those using Windows-based versions of Office can rest assured that patches to fix this issue is already available. However,  those still using Office 2016 for Mac and Office 2019 for Mac will have to wait a bit longer.

  • LNK

It seems that one of the CVEs fixed this month is one related to the LNK feature. Curiously enough, it seems to be the third time this year a CVE relate to this component gets discovered.

More so, CVE-2020-1299 behaves pretty much like the past ones, where an attacker could potentially exploit it to get code execution.

  • OLE data structures

CVE-2020-1281 is a bit more special compared to the rest since it can be used on all versions of Windows 10.

By exploiting this vulnerability, an attacked could get code execution rights if they can manage to make the user open certain files or programs.

  • CAB files

Another nasty CVE fixed this month is CVE-2020-1300 where attackers could gain code execution rights to certain systems by simply making users open modified CAB files.
