Descriptions
Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE), prior to 14.2 RU2 MP1 and prior to 14.2.5569.2100 respectively, may be susceptible to an out of bounds vulnerability, which is a type of issue that results in an existing application reading memory outside of the bounds of the memory that had been allocated to the program.
Symantec Endpoint Protection (SEP) y Symantec Endpoint Protection Small Business Edition (SEP SBE), versiones anteriores a 14.2 RU2 MP1 y versiones anteriores a 14.2.5569.2100 respectivamente, pueden ser susceptibles a una vulnerabilidad fuera de límites, que es un tipo de problema que resulta en que una aplicación existente lea la memoria fuera de los límites de la memoria que ha sido asignada al programa.
This vulnerability allows local attackers to disclose sensitive information on affected installations of Symantec Endpoint Protection Manager. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the AvHostPlugin.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a read before the start of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
