Trust: 0.8

sources: JVNDB: JVNDB-2018-005433

DESCRIPTION

A Time-of-Check Time-of-Use privilege escalation vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within processing of IOCTL 0x222813 by the tmusa driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. Trend Micro Maximum Security (Consumer) Contains a race condition vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The code is subject to a time-of-check/time-of-use race condition when processing data from the user. An attacker can leverage this vulnerability to escalate privileges to kernel. Failed exploit attempts will likely cause a denial-of-service condition.
