| CVE-2020-23907 | 1 Avast | 1 Retdec | 2021-04-26 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in retdec v3.3. In function canSplitFunctionOn() of ir_modifications.cpp, there is a possible out of bounds read due to a heap buffer overflow. The impact is: Deny of Service, Memory Disclosure, and Possible Code Execution. | |||||
| CVE-2021-27241 | 1 Avast | 1 Premium Security | 2021-04-01 | 3.6 LOW | 6.1 MEDIUM |
| This vulnerability allows local attackers to delete arbitrary directories on affected installations of Avast Premium Security 20.8.2429 (Build 20.8.5653.561). 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 AvastSvc.exe module. By creating a directory junction, an attacker can abuse the service to delete a directory. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-12082. | |||||
| CVE-2015-8620 | 1 Avast | 4 Avast Free Antivirus, Avast Internet Security, Avast Premier and 1 more | 2021-03-26 | 7.2 HIGH | 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-2020-25289 | 1 Avast | 1 Secureline Vpn | 2020-09-17 | 2.1 LOW | 5.5 MEDIUM |
| The VPN service in AVAST SecureLine before 5.6.4982.470 allows local users to write to arbitrary files via an Object Manager symbolic link from the log directory (which has weak permissions). | |||||

| 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-2020-10865 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2020-04-02 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Avast Antivirus before 20. The aswTask RPC endpoint for the TaskEx library in the Avast Service (AvastSvc.exe) allows attackers to make arbitrary changes to the Components section of the Stats.ini file via RPC from a Low Integrity process. | |||||
| CVE-2020-10866 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2020-04-02 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Avast Antivirus before 20. The aswTask RPC endpoint for the TaskEx library in the Avast Service (AvastSvc.exe) allows attackers to enumerate the network interfaces and access points from a Low Integrity process via RPC. | |||||
| CVE-2020-10867 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2020-04-02 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in Avast Antivirus before 20. The aswTask RPC endpoint for the TaskEx library in the Avast Service (AvastSvc.exe) allows attackers to bypass intended access restrictions on tasks from an untrusted process, when Self Defense is enabled. | |||||
| CVE-2020-8987 | 1 Avast | 2 Antitrack, Avg Antitrack | 2020-03-10 | 5.8 MEDIUM | 7.4 HIGH |
| Avast AntiTrack before 1.5.1.172 and AVG Antitrack before 2.0.0.178 proxies traffic to HTTPS sites but does not validate certificates, and thus a man-in-the-middle can host a malicious website using a self-signed certificate. No special action necessary by the victim using AntiTrack with "Allow filtering of HTTPS traffic for tracking detection" enabled. (This is the default configuration.) | |||||
| CVE-2019-18893 | 3 Avast, Avg, Video Downloader Project | 3 Secure Browser, Secure Browser, Video Downloader | 2020-01-22 | 4.3 MEDIUM | 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-2019-18894 | 1 Avast | 1 Premium Security | 2020-01-21 | 9.3 HIGH | 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-2019-18653 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2019-11-06 | 4.3 MEDIUM | 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-2017-8307 | 1 Avast | 1 Antivirus | 2019-10-02 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 2019-10-02 | 7.2 HIGH | 6.7 MEDIUM |
| 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-2017-8308 | 1 Avast | 1 Antivirus | 2019-10-02 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-11230 | 1 Avast | 1 Antivirus | 2019-07-24 | 3.6 LOW | 4.4 MEDIUM |
| 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-2007-2845 | 1 Avast | 1 Avast Antivirus | 2018-10-16 | 9.3 HIGH | N/A |
| Heap-based buffer overflow in the CAB unpacker in avast! Anti-Virus Managed Client before 4.7.700 allows user-assisted remote attackers to execute arbitrary code via a crafted CAB archive, resulting from an "integer cast around". | |||||
| CVE-2007-1673 | 9 Amavis, Avast, Avira and 6 more | 13 Amavis, Avast Antivirus, Avast Antivirus Home and 10 more | 2018-10-16 | 7.8 HIGH | N/A |
| unzoo.c, as used in multiple products including AMaViS 2.4.1 and earlier, allows remote attackers to cause a denial of service (infinite loop) via a ZOO archive with a direntry structure that points to a previous file. | |||||
| CVE-2007-1672 | 1 Avast | 1 Avast Antivirus | 2018-10-16 | 7.8 HIGH | N/A |
| avast! antivirus before 4.7.981 allows remote attackers to cause a denial of service (infinite loop) via a ZOO archive with a direntry structure that points to a previous file. | |||||
