| 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-2019-17093 | 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-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-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. | ||||
| CVE-2024-9483 | 2 Avast, Avg | 2 Antivirus, Antivirus | 2024-11-08 | 5.1 Medium |
| 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. | ||||
| CVE-2024-9482 | 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 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. | ||||
| CVE-2024-5102 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2024-08-01 | 7.0 High |
| A sym-linked file accessed via the repair function in Avast Antivirus <24.2 on Windows may allow user to elevate privilege to delete arbitrary files or run processes as NT AUTHORITY\SYSTEM. The vulnerability exists within the "Repair" (settings -> troubleshooting -> repair) feature, which attempts to delete a file in the current user's AppData directory as NT AUTHORITY\SYSTEM. A low-privileged user can make a pseudo-symlink and a junction folder and point to a file on the system. This can provide a low-privileged user an Elevation of Privilege to win a race-condition which will re-create the system files and make Windows callback to a specially-crafted file which could be used to launch a privileged shell instance. This issue affects Avast Antivirus prior to 24.2. | ||||
