TITLE

Trend Micro Maximum Security Vulnerable to out-of-bounds reading

Trust: 0.8

sources: JVNDB: JVNDB-2018-005431

DESCRIPTION

An Out-of-Bounds Read Information Disclosure vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to disclose sensitive information on vulnerable installations due to a flaw within processing of IOCTL 0x222814 by the tmnciesc.sys driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges to kernel. Failed exploit attempts will likely cause a denial-of-service condition. The following products and versions are vulnerable: Premium Security 12.0 and prior Maximum Security 12.0 and prior Internet Security 12.0 and prior Antivirus + Security 12.0 and prior

Trust: 2.52
