Kaspersky has fixed a security issue in Kaspersky Anti-Virus SDK for Windows, Kaspersky Security for Virtualization Light Agent, Kaspersky Endpoint Security for Windows, Kaspersky Small Office Security, Kaspersky for Windows (Standard, Plus, Premium), Kaspersky Free, Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Security Cloud, Kaspersky Safe Kids, Kaspersky Anti-Ransomware Tool that could allow an authenticated attacker to write data to a limited area outside the allocated kernel memory buffer. The fix was installed automatically for all Kaspersky Endpoint products.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The vulnerability potentially allowed an attacker to misuse ESET’s file operations during the removal of a detected file on the Windows operating system to delete files without having proper permissions to do so.

Local privilege escalation vulnerability allowed an attacker to misuse ESET's file operations during a restore operation from quarantine.

Avast Premium Security Sandbox Protection Link Following Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Avast Premium Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the implementation of the sandbox feature. By creating a symbolic link, an attacker can abuse the service to create arbitrary namespace objects. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. . Was ZDI-CAN-20383.

Avast Premium Security Sandbox Protection Incorrect Authorization Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Avast Premium Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the implementation of the sandbox feature. The issue results from incorrect authorization. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code outside the sandbox at medium integrity. . Was ZDI-CAN-20178.

Unquoted service path in ESET products allows to drop a prepared program to a specific location and run on boot with the NT AUTHORITY\NetworkService permissions.

Trend Micro uiAirSupport, included in the Trend Micro Security 2023 family of consumer products, version 6.0.2092 and below is vulnerable to a DLL hijacking/proxying vulnerability, which if exploited could allow an attacker to impersonate and modify a library to execute code on the system and ultimately escalate privileges on an affected system.

Trend Micro Security 2021, 2022, and 2023 (Consumer) are vulnerable to a DLL Hijacking vulnerability which could allow an attacker to use a specific executable file as an execution and/or persistence mechanism which could execute a malicious program each time the executable file is started.

Multiple DLL hijacking vulnerabilities via the components instup.exe and wsc_proxy.exe in Avast Premium Security before v21.11.2500 allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via a crafted DLL file.
