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 a denial of service vulnerability, which is a type of issue whereby a threat actor attempts to tie up the resources of a resident application, thereby making certain functions unavailable.
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 de denegación de servicio, que es un tipo de problema por el cual un actor de amenaza intenta vincular los recursos de una aplicación residente, haciendo de esta manera que determinadas funciones no estén disponibles.
This vulnerability allows local attackers to create a denial-of-service condition on affected installations of Symantec Endpoint Protection. 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 module. By invoking a method of a COM class, an attacker can delete arbitrary files. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
