A memory corruption vulnerability (CVE-2020-16875) in Microsoft Trade software is well worth highlighting all the critical flaws. The exploitation of this flaw could allow an attacker to operate arbitrary code at the Technique stage by sending a specifically crafted e-mail to a susceptible Exchange Server.

“A remote code execution vulnerability exists in Microsoft Exchange computer software when the software package fails to thoroughly deal with objects in memory,” Microsoft points out. “An attacker could then set up programs view, modify, or delete details or create new accounts.”

Microsoft also patched two vital remote code execution flaws in Home windows Codecs Library both exist in the way that Microsoft Home windows Codecs Library handles objects in memory, but although just one (CVE-2020-1129) could be exploited to get hold of facts to compromise the user’s process even further, the other (CVE-2020-1319) could be utilised to get management of the influenced process.
