CVSS v3.1 |
| AVAST Antivirus 25.11 contains an unquoted service path vulnerability in the SecureLine service that allows local non-privileged users to execute code with elevated SYSTEM privileges. Attackers can exploit the unquoted binary path in the service configuration to inject malicious executables that execute with high-level system permissions. |
| The socket connection handler in aswArPot.sys in the Avast and AVG Windows Anti Rootkit driver before 22.1 allows local attackers to execute arbitrary code in kernel mode or cause a denial of service (memory corruption and OS crash) due to a double fetch vulnerability at aswArPot+0xc4a3. |
| The socket connection handler in aswArPot.sys in the Avast and AVG Windows Anti Rootkit driver before 22.1 allows local attackers to execute arbitrary code in kernel mode or cause a denial of service (memory corruption and OS crash) due to a double fetch vulnerability at aswArPot+0xbb94. |
| avast! antivirus 4.8.1281.0, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit. |
| aavmker4.sys in avast! Home and Professional 4.7 for Windows does not properly validate input to IOCTL 0xb2d60030, which allows local users to gain privileges via certain IOCTL requests. |
| Multiple stack-based buffer overflows in avast! Linux Home Edition 1.0.5, 1.0.5-1, and 1.0.8 allow remote attackers to cause a denial of service (application crash) or execute arbitrary code via a malformed (1) ISO or (2) RPM file. |
| aavmKer4.sys in avast! Home and Professional for Windows before 4.8.1356 does not properly validate input to IOCTLs (1) 0xb2d6000c and (2) 0xb2d60034, which allows local users to gain privileges via IOCTL requests using crafted kernel addresses that trigger memory corruption, a different vulnerability than CVE-2008-1625. |
| Stack-based buffer overflow in aswMon2.sys in avast! Home and Professional for Windows 4.8.1351, and possibly other versions before 4.8.1356, allows local users to cause a denial of service (system crash) and possibly gain privileges via a crafted IOCTL request to IOCTL 0xb2c80018. |
| Unspecified vulnerability in ashWsFtr.dll in avast! Home and Professional for Windows before 4.8.1356 has unknown impact and local attack vectors. |
| 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. |
| Avast SecureLine 5.5.522.0 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted path in the service configuration to inject malicious code that would execute with LocalSystem account permissions during service startup. |
| Heap-based Buffer Overflow, Out-of-bounds Write vulnerability in Avast Antivirus on MacOS of a crafted Mach-O file may allow Local Execution of Code or Denial of Service of antivirus protection.
This issue affects Antivirus: from 15.7 before 3.9.2025. |
| Integer Overflow or Wraparound vulnerability in Avast Antivirus (25.1.981.6) on Windows allows Privilege Escalation.This issue affects Antivirus: from 25.1.981.6 before 25.3. |
| Double fetch in sandbox kernel driver in Avast/AVG Antivirus <25.3 on windows allows local attacker to escalate privelages via pool overflow. |
| Heap-based Buffer Overflow, Out-of-bounds Read vulnerability in Avast Antivirus on MacOS when scanning a malformed file may allow Local Execution of Code or Denial-of-Service of the anitvirus engine process.This issue affects Antivirus: from 8.3.70.94 before 8.3.70.98. |
| NULL Pointer Dereference vulnerability in Avast Antivirus on MacOS, Avast Anitvirus on Linux when scanning a malformed Windows PE file causes the antivirus process to crash.This issue affects Antivirus: 16.0.0; Anitvirus: 3.0.3. |
| Collision in MiniFilter driver in Avast Software Avast Free Antivirus before 25.9 on Windows allows a local attacker with administrative privileges to disable real-time protection and self-defense mechanisms. |
| Link Following Local Privilege Escalation Vulnerability in NortonUtilitiesSvc in Norton Utilities Ultimate Version 24.2.16862.6344 on Windows 10 Pro x64 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via the creation of a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
| 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. |
| 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. |
