Windows User Profile Service Elevation of Privilege Vulnerability

An improper link resolution before file access ('link following') vulnerability exists in the Palo Alto Networks GlobalProtect app on Windows that enables a local attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges under certain circumstances. This issue impacts: GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.10 on Windows. GlobalProtect app 5.2 versions earlier than GlobalProtect app 5.2.5 on Windows. This issue does not affect GlobalProtect app on other platforms.

snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1

Trendnet AC2600 TEW-827DRU version 2.08B01 contains a symlink vulnerability in the bittorrent functionality. If enabled, the bittorrent functionality is vulnerable to a symlink attack that could lead to remote code execution on the device. If an end user inserts a flash drive with a malicious symlink on it that the bittorrent client can write downloads to, then a user is able to download arbitrary files to any desired location on the devices filesystem, which could lead to remote code execution. Example directories vulnerable to this include "config", "downloads", and "torrents", though it should be noted that "downloads" is the only vector that allows for arbitrary files to be downloaded to arbitrary locations.

NVIDIA GeForce Experience before 3.18 contains a vulnerability when ShadowPlay or GameStream is enabled.
