| CVE-2020-10860 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2024-11-21 | 7.5 High |
| An issue was discovered in Avast Antivirus before 20. An Arbitrary Memory Address Overwrite vulnerability in the aswAvLog Log Library results in Denial of Service of the Avast Service (AvastSvc.exe). | ||||
| CVE-2019-18894 | 1 Avast | 1 Premium Security | 2024-11-21 | 7.8 High |
| In Avast Premium Security 19.8.2393, attackers can send a specially crafted request to the local web server run by Avast Antivirus on port 27275 to support Bank Mode functionality. A flaw in the processing of a command allows execution of arbitrary OS commands with the privileges of the currently logged in user. This allows for example attackers who compromised a browser extension to escape from the browser sandbox. | ||||
| 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-2016-4025 | 1 Avast | 11 Business Security, Email Server Security, Endpoint Protection and 8 more | 2024-11-21 | N/A |
| Avast Internet Security v11.x.x, Pro Antivirus v11.x.x, Premier v11.x.x, Free Antivirus v11.x.x, Business Security v11.x.x, Endpoint Protection v8.x.x, Endpoint Protection Plus v8.x.x, Endpoint Protection Suite v8.x.x, Endpoint Protection Suite Plus v8.x.x, File Server Security v8.x.x, and Email Server Security v8.x.x allow attackers to bypass the DeepScreen feature via a DeviceIoControl call. | ||||
| CVE-2016-3986 | 1 Avast | 1 Avast | 2024-11-21 | N/A |
| Avast allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via a crafted PE file, related to authenticode parsing. | ||||
| CVE-2015-8620 | 1 Avast | 4 Avast Free Antivirus, Avast Internet Security, Avast Premier and 1 more | 2024-11-21 | 7.8 High |
| Heap-based buffer overflow in the Avast virtualization driver (aswSnx.sys) in Avast Internet Security, Pro Antivirus, Premier, and Free Antivirus before 11.1.2253 allows local users to gain privileges via a Unicode file path in an IOCTL request. | ||||
| CVE-2015-5662 | 1 Avast | 1 Avast Antivirus | 2024-11-21 | N/A |
| Directory traversal vulnerability in Avast before 150918-0 allows remote attackers to delete or write to arbitrary files via a crafted entry in a ZIP archive. | ||||
| CVE-2013-0122 | 1 Avast | 1 Avast\! Mobile Security | 2024-11-21 | N/A |
| The avast! Mobile Security application before 2.0.4400 for Android allows attackers to cause a denial of service (application crash) via a crafted application that sends an intent to com.avast.android.mobilesecurity.app.scanner.DeleteFileActivity with zero arguments. | ||||
| CVE-2010-3126 | 1 Avast | 1 Avast Antivirus Free | 2024-11-21 | N/A |
| Untrusted search path vulnerability in avast! Free Antivirus version 5.0.594 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse mfc90loc.dll that is located in the same folder as an avast license (.avastlic) file. | ||||
| CVE-2010-0705 | 2 Avast, Microsoft | 4 Avast Antivirus Home, Avast Antivirus Professional, Windows 2000 and 1 more | 2024-11-21 | N/A |
| Aavmker4.sys in avast! 4.8 through 4.8.1368.0 and 5.0 before 5.0.418.0 running on Windows 2000 and XP does not properly validate input to IOCTL 0xb2d60030, which allows local users to cause a denial of service (system crash) or execute arbitrary code to gain privileges via IOCTL requests using crafted kernel addresses that trigger memory corruption. | ||||
| CVE-2009-4049 | 1 Avast | 2 Avast Antivirus Home, Avast Antivirus Professional | 2024-11-21 | N/A |
| Heap-based buffer overflow in aswRdr.sys (aka the TDI RDR driver) in avast! Home and Professional 4.8.1356.0 allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted arguments to IOCTL 0x80002024. | ||||
| CVE-2009-3524 | 1 Avast | 2 Avast Antivirus Home, Avast Antivirus Professional | 2024-11-21 | N/A |
