Microsoft April 2020 Patch Tuesday
This month we got patches for 113 vulnerabilities total. According to Microsoft, three of them are being exploited (CVE-2020-1020, CVE-2020-0938 and CVE-2020-0968) and two were previously disclosed (CVE-2020-1020 and CVE-2020-0935).
Two of the exploited vulnerabilities (CVE-2020-1020 and CVE-2020-0938) are RCEs found by Google Project Zero in Adobe Font Manager Library. They exist in way the library improperly handles a specially-crafted multi-master font - Adobe Type 1 PostScript format. For all systems except Windows 10, an attacker who successfully exploited the vulnerabilities could execute code remotely. For systems running Windows 10, an attacker who successfully exploited the vulnerabilities could execute code in an AppContainer sandbox context with limited privileges and capabilities.
The other exploited vulnerability (CVE-2020-0968) is remote code execution vulnerability in Internet Explorer. It consists in the way the scripting engine handles objects in memory. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user.
The highest CVSS v3 score this month (8.80) was given to the vulnerability CVE-2020-0687. It is a RCE in Microsoft Graphics and exists due to the way the library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system.
