An issue was discovered in Xen through 4.14.x. A guest may access xenstore paths via absolute paths containing a full pathname, or via a relative path, which implicitly includes /local/domain/$DOMID for their own domain id. Management tools must access paths in guests’ namespaces, necessarily using absolute paths. oxenstored imposes a pathname limit that is applied solely to the relative or absolute path specified by the client. Therefore, a guest can create paths in its own namespace which are too long for management tools to access. Depending on the toolstack in use, a malicious guest administrator might cause some management tools and debugging operations to fail. For example, a guest administrator can cause “xenstore-ls -r” to fail. However, a guest administrator cannot prevent the host administrator from tearing down the domain. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
CWE-426
CVE-2020-27695
Trend Micro Security 2020 (Consumer) contains a vulnerability in the installer package that could be exploited by placing a malicious DLL in a local directory which can lead to obtaining administrative privileges during the installation of the product.
CVE-2020-15801
In Python 3.8.4, sys.path restrictions specified in a python38._pth file are ignored, allowing code to be loaded from arbitrary locations. The ._pth file (e.g., the python._pth file) is not affected.
CVE-2020-15602
An untrusted search path remote code execution (RCE) vulnerability in the Trend Micro Secuity 2020 (v16.0.0.1146 and below) consumer family of products could allow an attacker to run arbitrary code on a vulnerable system. As the Trend Micro installer tries to load DLL files from its current directory, an arbitrary DLL could also be loaded with the same privileges as the installer if run as Administrator. User interaction is required to exploit the vulnerbaility in that the target must open a malicious directory or device.
CVE-2020-15009
AsusScreenXpertServicec.exe and ScreenXpertUpgradeServiceManager.exe in ScreenPad2_Upgrade_Tool.msi V1.0.3 for ASUS PCs with ScreenPad 1.0 (UX450FDX, UX550GDX and UX550GEX) could lead to unsigned code execution with no additional restrictions when a user puts an application at a particular path with a particular file name.
CVE-2020-1458
A remote code execution vulnerability exists when Microsoft Office improperly validates input before loading dynamic link library (DLL) files, aka ‘Microsoft Office Remote Code Execution Vulnerability’.
