We have investigated reports of a spoofing vulnerability in AppX installer that affects Microsoft Windows. Microsoft is aware of attacks that attempt to exploit this vulnerability by using specially crafted packages that include the malware family known as Emotet/Trickbot/Bazaloader. An attacker could craft a malicious attachment to be used in phishing campaigns. The attacker would then have to convince the user to open the specially crafted attachment. 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. Please see the Security Updates table for the link to the updated app. Alternatively you can download and install the Installer using the links provided in the FAQ section. Please see the Mitigations and Workaround sections for important information about steps you can take to protect your system from this vulnerability.

A time-of-check time-of-use vulnerability in PulseSecureService.exe in Pulse Secure Client versions prior to 9.1.6 down to 5.3 R70 for Windows (which runs as NT AUTHORITY/SYSTEM) allows unprivileged users to run a Microsoft Installer executable with elevated privileges.

Flash Player versions 31.0.0.153 and earlier, and 31.0.0.108 and earlier have a use after free vulnerability. Successful exploitation could lead to arbitrary code execution.

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Incorrect default permissions for some Intel(R) GPA and Intel(R) GPA Framework software installers may allow an authenticated user to potentially enable escalation of privilege via local access.

Improper access control in some Intel(R) Graphics Driver software installers may allow an authenticated user to potentially enable escalation of privilege via local access.

Incorrect default permissions for some Intel(R) DSA installer for Windows before version 24.2.19.5 may allow an authenticated user to potentially enable escalation of privilege via local access.

Improper access control in some Intel(R) ME driver pack installer engines before version 2422.6.2.0 may allow an authenticated user to potentially enable escalation of privilege via local access.

A maliciously crafted DLL file when placed in temporary files and folders that are leveraged by the Autodesk Installer could lead to escalation of privileges to NT AUTHORITY/SYSTEM due to insecure privilege management.

Uncontrolled search path in the Intel(R) Graphics Driver installers for versions 15.40 and 15.45 may allow an authenticated user to potentially enable escalation of privilege via local access.
