Title
Avast sandbox escape via unpreserved COM pathway through Task Scheduler
Summary
Improper isolation in the Avast sandbox on Windows allows a local, low-privileged attacker executing inside the sandbox to access COM interfaces to the Task Scheduler service, escape containment, and execute code with elevated privileges outside the sandbox.
The sandbox virtualizes file system and registry access but does not adequately restrict COM interface access to Task Scheduler. A process inside the sandbox can instantiate COM objects bound to Task Scheduler functionality and invoke methods to schedule and execute tasks on the host system. The Task Scheduler COM pathway is not blocked by the sandbox policy, allowing arbitrary code execution in the host security context.
This escape vector bypasses the sandbox's intended process and file isolation boundaries and can be chained with other host-level privilege escalation techniques.

Title
Avast sandbox escape via arbitrary file write in virtualized environment
Summary
Insufficient isolation in the Avast sandbox file virtualization layer on Windows allows a local, low-privileged attacker executing inside the sandbox to write arbitrary files outside sandbox containment and execute code on the host.
The sandbox virtualizes file system operations by intercepting write requests to protected system directories. However, the virtualization implementation fails to properly validate write targets in certain edge cases, allowing writes to bypass the virtualization redirection and reach the actual host file system in protected locations.
An attacker can exploit this to overwrite executable files, system libraries, or startup configurations with arbitrary content, leading to code execution with host privileges on subsequent system operations or reboot.

Title
Avast WFP stream parser integer underflow causes system crash
Summary
An integer underflow vulnerability in the Avast Windows Filtering Platform (WFP) stream parser on Windows allows denial of service by causing a system crash.
The WFP callout driver processes network stream data and computes length values for packet fragment reassembly. The length calculation does not properly validate input stream sizes against expected boundaries. When processing specially crafted input, the length computation underflows, resulting in allocation or buffer access with an extremely large wrapped-around size value.
The underflow can be triggered remotely via network traffic destined for the filtered port, or locally via crafted data provided to the filtering interface. The resulting memory allocation failure or out-of-bounds access causes a kernel panic and system crash.

CVE-2026-12067 (GCVE-0-2026-12067)

Title
AvastSvc denial of service via unhandled JsonCpp exceptions in native message handlers
Summary
Missing exception handlers in AvastSvc native message dispatcher (ashServ.dll) on Windows allow a local, unprivileged attacker to crash the service by sending specially crafted JSON messages.
The vulnerability spans multiple handler pathways in the RPC-based native message protocol:
* Log_NmSvc.message handler: converts JSON fields to strings without type validation and without exception boundaries.
* OpenInSz_NmSvc handler: converts URL and origin fields to strings without type checking, exposing an exception.
* OpenInSz_NmSvc.profile handler: converts the profile field to an integer without validation.
In all three cases, the exceptions are not caught by action-specific handlers and propagate up the dispatcher. The common root cause is the absence of try-catch blocks around JSON type conversions in the native message processing chain.

Title
Avast sandbox privilege escalation via unpreserved DACLs on virtualized files in aswSnx.sys
Summary
Improper preservation of permissions in the Avast sandbox minifilter driver (aswSnx.sys) on Windows allows a local, low-privileged attacker executing inside the sandbox to escape file isolation and escalate to SYSTEM.
When the sandbox virtualizes a file it copies the original security descriptor, but the driver opened the virtualization target object with GENERIC_WRITE and FILE_WRITE_ATTRIBUTES only, omitting WRITE_DAC. Every attempt to apply the original DACL therefore failed, and the failure was discarded silently, leaving virtualized copies of sensitive files with permissive permissions. Because the IRP_MJ_CREATE callback additionally did not strip WRITE_DAC for sensitive directories, a sandboxed process could rewrite the security descriptor of a virtualized object, read the virtualized copy of the SAM database, extract local NTLM password hashes and execute code as SYSTEM.
The absence of an IRP_MJ_SET_SECURITY callback in the driver's operation registration table is a related defense-in-depth gap, but it is not the control that prevents this attack.

Title
Avast antivirus stack overflow when scanning a malformed Office Open XML file
Summary
Stack overflow vulnerability in Avast Antivirus when scanning a malformed Office Open XML file may allow Denial-of-Service of the antivirus process.
This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25020100.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.

Title
Avast antivirus heap OOB when scanning a malformed zip file
Summary
Heap out-of-bounds read vulnerability in Avast Antivirus when scanning a malformed zip file containing XML may allow Local Execution of Code or Denial-of-Service of the antivirus process.
This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds from 25020100 before 25021208.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.

Title
Avast antivirus use of stack memory after free when scanning a malformed PE file
Summary
Use of stack memory after free vulnerability in Avast Antivirus when scanning a malformed Windows PE file may allow Denial-of-Service of the antivirus process.
This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25022500.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.

Title
Avast antivirus heap buffer OOB write when scanning a malformed PE file
Summary
Heap buffer out-of-bounds write vulnerability in Avast Antivirus when scanning a malformed Windows PE file may allow Local Execution of Code or Denial-of-Service of the antivirus process.
This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25040308.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.
