Vulnerability from variot

McAfee Network Agent (mcnasvc.exe) 1.0.178.0, as used by multiple McAfee products possibly including Internet Security Suite, Personal Firewall Plus, and VirusScan, allows remote attackers to cause a denial of service (agent crash) via a long packet, possibly because of an invalid string position field value. NOTE: some of these details are obtained from third party information. McAfee Network Agent is prone to a remote denial-of-service vulnerability because the service fails to properly handle excessive network data. Exploiting this issue may cause the affected application to crash, denying service to legitimate users. Version 1.0.178.0 is vulnerable; other versions may also be affected. Remote attackers may use this vulnerability to perform denial of service attacks on services.

Want to work within IT-Security?

Secunia is expanding its team of highly skilled security experts. We will help with relocation and obtaining a work permit. This can be exploited to crash the service by sending a specially crafted message with an invalid value in the string position field.

SOLUTION: Restrict access to the service.
