SB2018122507 - Privilege escalation in IBM Trusteer Rapport

Description

This security bulletin contains information about 1 security vulnerability.

1) Stack-based buffer overflow (CVE-ID: N/A)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to a signedness bug in validating the user-supplied number of elements provided by the user in the structure passed to the Kernel driver function. A local attacker can perform a call to an struct method exported from the Kernel driver with the IOService 'com_trusteer_rapportke_v2', trigger stack-based buffer overflow and execute arbitrary code in the context of the service daemon.

Successful exploitation of the vulnerability may result in system compromise.

Remediation

Cybersecurity Help is not aware of any official remediation provided by the vendor.
