| CVE-2019-18893 | 3 Avast, Avg, Video Downloader Project | 3 Secure Browser, Secure Browser, Video Downloader | 2024-11-21 | 6.1 Medium |
| XSS in the Video Downloader component before 1.5 of Avast Secure Browser 77.1.1831.91 and AVG Secure Browser 77.0.1790.77 allows websites to execute their code in the context of this component. While Video Downloader is technically a browser extension, it is granted a very wide set of privileges and can for example access cookies and browsing history, spy on the user while they are surfing the web, and alter their surfing experience in almost arbitrary ways. | ||||
| CVE-2019-18653 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2024-11-21 | 6.1 Medium |
| A Cross Site Scripting (XSS) issue exists in Avast AntiVirus (Free, Internet Security, and Premiere Edition) 19.3.2369 build 19.3.4241.440 in the Network Notification Popup, allowing an attacker to execute JavaScript code via an SSID Name. | ||||
| CVE-2019-17190 | 1 Avast | 1 Secure Browser | 2024-11-21 | 7.8 High |
| A Local Privilege Escalation issue was discovered in Avast Secure Browser 76.0.1659.101. The vulnerability is due to an insecure ACL set by the AvastBrowserUpdate.exe (which is running as NT AUTHORITY\SYSTEM) when AvastSecureBrowser.exe checks for new updates. When the update check is triggered, the elevated process cleans the ACL of the Update.ini file in %PROGRAMDATA%\Avast Software\Browser\Update\ and sets all privileges to group Everyone. Because any low-privileged user can create, delete, or modify the Update.ini file stored in this location, an attacker with low privileges can create a hard link named Update.ini in this folder, and make it point to a file writable by NT AUTHORITY\SYSTEM. Once AvastBrowserUpdate.exe is triggered by the update check functionality, the DACL is set to a misconfigured value on the crafted Update.ini and, consequently, to the target file that was previously not writable by the low-privileged attacker. | ||||
| CVE-2019-17093 | 2 Avast, Avg | 2 Antivirus, Anti-virus | 2024-11-21 | 7.8 High |
| An issue was discovered in Avast antivirus before 19.8 and AVG antivirus before 19.8. A DLL Preloading vulnerability allows an attacker to implant %WINDIR%\system32\wbemcomn.dll, which is loaded into a protected-light process (PPL) and might bypass some of the self-defense mechanisms. This affects all components that use WMI, e.g., AVGSvc.exe 19.6.4546.0 and TuneupSmartScan.dll 19.1.884.0. | ||||
| CVE-2019-11230 | 1 Avast | 1 Antivirus | 2024-11-21 | N/A |
| In Avast Antivirus before 19.4, a local administrator can trick the product into renaming arbitrary files by replacing the Logs\Update.log file with a symlink. The next time the product attempts to write to the log file, the target of the symlink is renamed. This defect can be exploited to rename a critical product file (e.g., AvastSvc.exe), causing the product to fail to start on the next system restart. | ||||
| CVE-2018-12572 | 1 Avast | 1 Free Antivirus | 2024-11-21 | N/A |
| Avast Free Antivirus prior to 19.1.2360 stores user credentials in memory upon login, which allows local users to obtain sensitive information by dumping AvastUI.exe application memory and parsing the data. | ||||
| CVE-2017-8308 | 1 Avast | 1 Antivirus | 2024-11-21 | N/A |
| In Avast Antivirus before v17, an unprivileged user (and thus malware or a virus) can mark an arbitrary process as Trusted from the perspective of the Avast product. This bypasses the Self-Defense feature of the product, opening a door to subsequent attack on many of its components. | ||||
| CVE-2017-8307 | 1 Avast | 1 Antivirus | 2024-11-21 | N/A |
| In Avast Antivirus before v17, using the LPC interface API exposed by the AvastSVC.exe Windows service, it is possible to launch predefined binaries, or replace or delete arbitrary files. This vulnerability is exploitable by any unprivileged user when Avast Self-Defense is disabled. It is also exploitable in conjunction with CVE-2017-8308 when Avast Self-Defense is enabled. The vulnerability allows for Denial of Service attacks and hiding traces of a possible attack. | ||||
| CVE-2017-5567 | 1 Avast | 4 Free Antivirus, Internet Security, Premier and 1 more | 2024-11-21 | N/A |
| Code injection vulnerability in Avast Premier 12.3 (and earlier), Internet Security 12.3 (and earlier), Pro Antivirus 12.3 (and earlier), and Free Antivirus 12.3 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Avast process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack. | ||||
| CVE-2024-9484 | 2 Avast, Avg | 2 Antivirus, Antivirus | 2024-11-08 | 5.1 Medium |
| An null-pointer-derefrence in the engine module in AVG/Avast Antivirus signature <24092400 released on 24/Sep/2024 on MacOS allows a malformed xar file to crash the application during file processing. | ||||

| A null-pointer-dereference in the signature verification module in AVG/Avast Antivirus signature <24092400 released on 24/Sep/2024 on MacOS may allow a malformed xar file to crash the application during processing. | ||||

| An out-of-bounds write in the engine module in AVG/Avast Antivirus signature <24092400 released on 24/Sep/2024 on MacOS allows a malformed Mach-O file to crash the application during file processing. | ||||
| CVE-2024-9481 | 2 Avast, Avg | 2 Antivirus, Antivirus | 2024-11-08 | 5.1 Medium |
| An out-of-bounds write in the engine module in AVG/Avast Antivirus signature <24092400 released on 24/Sep/2024 on MacOS allows a malformed eml file to crash the application during file processing. | ||||
