Adobe released patch for one vulnerability in FLASH Player | | APSB20-58
Adobe has released security updates of Adobe Flash Player for Windows, macOS, Linux and Chrome OS. These updates address a critical vulnerability in Adobe Flash Player. Successful exploitation could lead to an exploitable crash, potentially resulting in arbitrary code execution in the context of the current user. So please update your Adobe version too.
Following some of the CVE’s are critical.
- CVE-2020-16898 | Windows TCP/IP Remote Code Execution Vulnerability
A remote code execution vulnerability exists when the Windows TCP/IP stack improperly handles ICMPv6 Router Advertisement packets. An attacker who successfully exploited this vulnerability could gain the ability to execute code on the target server or client.
To exploit this vulnerability, an attacker would have to send specially crafted ICMPv6 Router Advertisement packets to a remote Windows computer.
The update addresses the vulnerability by correcting how the Windows TCP/IP stack handles ICMPv6 Router Advertisement packets.
- CVE-2020-16947 | Microsoft Outlook Remote Code Execution Vulnerability
A remote code execution vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the System user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system.
An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Outlook software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file designed to exploit the vulnerability.
An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.
Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector.
The security update addresses the vulnerability by correcting how Outlook handles objects in memory
- CVE-2020-16909 | Windows Error Reporting Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists in Windows Error Reporting (WER) when WER handles and executes files. The vulnerability could allow elevation of privilege if an attacker can successfully exploit it.
An attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. To exploit the vulnerability, an attacker could run a specially crafted application.
The security update addresses the vulnerability by correcting the way that WER handles and executes files.
Please note the following information regarding the security updates:
- Microsoft is improving Windows Release Notes. For more information, please see What’s next for Windows release notes.
