Norton Security (Windows client) prior to 22.16.3 and SEP SBE (Windows client) prior to Cloud Agent 3.00.31.2817, NIS-22.15.2.22 & SEP-12.1.7484.7002, may be susceptible to a DLL Preloading vulnerability, which is a type of issue that can occur when an application looks to call a DLL for execution and an attacker provides a malicious DLL to use instead.

Symantec Norton Security prior to 22.16.3, SEP (Windows client) prior to and including 12.1 RU6 MP9, and prior to 14.2 RU1, SEP SBE prior to Cloud Agent 3.00.31.2817, NIS-22.15.2.22, SEP-12.1.7484.7002 and SEP Cloud prior to 22.16.3 may be susceptible to a kernel memory disclosure, which is a type of issue where a specially crafted IRP request can cause the driver to return uninitialized memory.

A Privilege Escalation vulnerability exists in Symantec Norton Antivirus, Norton AntiVirus with Backup, Norton Security, Norton Security with Backup, Norton Internet Security, Norton 360, Endpoint Protection Small Business Edition Cloud, and Endpoint Protection Cloud Client due to a DLL-preloading without path restrictions, which could let a local malicious user obtain system privileges.
