Vulnerabilities in Alyac antivirus program could stop virus scanning, cause code execution

Cisco Talos recently discovered out-of-bounds read and buffer overflow vulnerabilities in ESTsecurity Corp.’s Alyac antivirus software that could cause a denial-of-service condition or arbitrary code execution. Alyac is an antivirus software developed for Microsoft Windows machines.

TALOS-2022-1452 (CVE-2022-21147) is a vulnerability that exists in a specific Alyac module that, eventually, leads to a crash of Alyac’s scanning process, which effectively neutralizes the antivirus scan.
