Azure Sphere Unsigned Code Execution Vulnerability

Azure Sphere Unsigned Code Execution Vulnerability

A spoofing vulnerability exists when Windows incorrectly validates file signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed files. In an attack scenario, an attacker could bypass security features intended to prevent improperly signed files from being loaded. The update addresses the vulnerability by correcting how Windows validates file signatures.

An elevation of privilege vulnerability exists when the OneDrive for Windows Desktop application improperly handles symbolic links, aka 'OneDrive for Windows Elevation of Privilege Vulnerability'.

<p>A security feature bypass vulnerability exists when a Windows Projected Filesystem improperly handles file redirections. An attacker who successfully exploited this vulnerability could delete a targeted file they would not have permissions to.</p> <p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability.</p> <p>The security update addresses the vulnerability by correcting how Windows Projected Filesystem handle file redirections.</p>

An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links, aka 'Windows Installer Elevation of Privilege Vulnerability'. This CVE ID is unique from CVE-2020-0798, CVE-2020-0814, CVE-2020-0842, CVE-2020-0843.

A security feature bypass vulnerability exists in Windows 10 when third party filters are called during a password update, aka 'Windows Security Feature Bypass Vulnerability'.

Incorrect command line processing in Chrome in Google Chrome prior to 73.0.3683.75 allowed a local attacker to perform domain spoofing via a crafted domain name.

Prior to SEP 12.1 RU6 MP9 & SEP 14 RU1 Symantec Endpoint Protection Windows endpoint can encounter a situation whereby an attacker could use the product's UI to perform unauthorized file deletes on the resident file system.

Microsoft Windows 10 Gold and 1511 allows local users to bypass the Virtual Secure Mode Hypervisor Code Integrity (HVCI) protection mechanism and perform RWX markings of kernel-mode pages via a crafted application, aka "Hypervisor Code Integrity Security Feature Bypass."

Windows AppContainer Firewall Rules Security Feature Bypass Vulnerability

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local user to gain privileges due to allowing modification of columns of existing tasks. IBM X-Force ID: 210321.

The kernel in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT Gold and 8.1, and Windows 10 Gold and 1511 allows local users to bypass intended filesystem permissions by leveraging Low Integrity access, aka "Windows Kernel Security Feature Bypass Vulnerability."

The Mozilla Maintenance Service "helper.exe" application creates a temporary directory writable by non-privileged users. When this is combined with creation of a junction (a form of symbolic link), protected files in the target directory of the junction can be deleted by the Mozilla Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.

Microsoft Windows 8.1 and Windows RT 8.1, Windows Server 2012 R2, Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allow an attacker to set variables that are either read-only or require authentication when Windows fails to enforce case sensitivity for certain variable checks, aka "Windows Security Feature Bypass Vulnerability".

The kernel-mode driver in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not properly constrain impersonation levels, which allows local users to gain privileges via a crafted application, aka "Windows KMD Security Feature Bypass Vulnerability."

The Windows shell in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT Gold and 8.1, and Windows 10 does not properly constrain impersonation levels, which allows local users to gain privileges via a crafted application, aka "Windows Shell Security Feature Bypass Vulnerability."

Object Manager in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not properly constrain impersonation levels during interaction with object symbolic links that originated in a sandboxed process, which allows local users to gain privileges via a crafted application, aka "Windows Object Manager Elevation of Privilege Vulnerability."

Sensitive information disclosure and manipulation due to insufficient authorization checks. The following products are affected: Acronis Cyber Protect 17 (Linux, macOS, Windows) before build 41186, Acronis Cyber Protect Cloud Agent (Linux, macOS, Windows) before build 41124.

The Task Scheduler in Microsoft Windows 7 SP1, Windows Server 2008 R2 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not properly constrain impersonation levels, which allows local users to bypass intended restrictions on launching executable files via a crafted task, aka "Task Scheduler Security Feature Bypass Vulnerability."
