Name of the Vulnerable Software and Affected Versions avast! Home and Professional versions 4.8.1351 through 4.8.1355

Description A stack-based buffer overflow issue exists, allowing local users to cause a system crash and possibly gain privileges. This is achieved by sending a crafted IOCTL request to the IOCTL 0xb2c80018 endpoint.

Recommendations For versions 4.8.1351 through 4.8.1355, update to version 4.8.1356 or later to resolve the issue. As a temporary workaround, consider restricting access to the aswMon2.sys driver to minimize the risk of exploitation.
