New! CVE Severity Now Using CVSS v3
The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Description
An attacker-controlled memory allocation size can be passed to the C++ new operator in RnaDaSvr.dll by sending a specially crafted ConfigureItems message to TCP port 4241. This will cause an unhandled exception, resulting in termination of RSLinxNG.exe. Observed in FactoryTalk 6.11. All versions of FactoryTalk Linx are affected.
