AI-suggested
Until an official patch is released, organizations should implement strict controls on the handling of .sym files, including disabling the automatic opening of such files and educating users about the risks of opening files from untrusted sources. Employ application whitelisting and sandboxing techniques to restrict the execution environment of NI Circuit Design Suite. Network segmentation can limit exposure of affected systems. Monitoring for anomalous behavior related to the SymbolEditor component may help detect exploitation attempts. Once patches become available from NI, prompt deployment is essential. Additionally, organizations should maintain up-to-date backups of critical design files and implement robust endpoint protection solutions capable of detecting exploitation attempts targeting memory corruption vulnerabilities.
Description
There is a memory corruption vulnerability due to an out of bounds read in DefaultFontOptions() when using SymbolEditor in NI Circuit Design Suite. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted .sym file. This vulnerability affects NI Circuit Design Suite 14.3.1 and prior versions.
