Eset » Smart Security » 3.0.669 : Security Vulnerabilities, CVEs,

Local privilege escalation vulnerability potentially allowed an attacker to misuse ESET’s file operations to delete files without having proper permission.

The ESET AV parsing engine allows virus-detection bypass via a crafted BZ2 Checksum field in an archive. This affects versions before 1294 of Smart Security Premium, Internet Security, NOD32 Antivirus, Cyber Security Pro (macOS), Cyber Security (macOS), Mobile Security for Android, Smart TV Security, and NOD32 Antivirus 4 for Linux Desktop.

The Personal Firewall driver (aka epfw.sys) 3.0.672.0 and earlier in ESET Smart Security 3.0.672 and earlier allows local users to gain privileges via a crafted IRP in a certain METHOD_NEITHER IOCTL request to \Device\Epfw that overwrites portions of memory.
