Quick Heal Total Security

Stack-based buffer overflow in Quick Heal Internet Security 10.1.0.316 and earlier, Total Security 10.1.0.316 and earlier, and AntiVirus Pro 10.1.0.316 and earlier on OS X allows remote attackers to execute arbitrary code via a crafted LC_UNIXTHREAD.cmdsize field in a Mach-O file that is mishandled during a Security Scan (aka Custom Scan) operation.

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Out of Bounds Write on a Heap Buffer due to improper validation of dwCompressionSize of Microsoft WIM Header WIMHEADER_V1_PACKED. This vulnerability can be exploited to gain Remote Code Execution as well as Privilege Escalation.

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Memory Corruption while parsing a malformed Mach-O file.

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Memory Corruption while parsing a malformed Mach-O file.

A vulnerability exists in Quick Heal Total Security 23.0.0 in the quarantine management component where insufficient validation of restore paths and improper permission handling allow a low-privileged local user to restore quarantined files into protected system directories. This behavior can be abused by a local attacker to place files in high-privilege locations, potentially leading to privilege escalation.

The webssx.sys driver in QuickHeal 16.00 allows remote attackers to cause a denial of service.
