Lenovo patches serious vulnerabilities in PC system update tool | CSO Online

For the third time in less than six months security issues have forced Lenovo to update one of the tools preloaded on its PCs.

Last week, the company released version 5.07.0019 of Lenovo System Update, a tool that helps users keep their computers' drivers and BIOS up to date and which was previously called ThinkVantage System Update. The new version fixes two local privilege escalation vulnerabilities discovered by researchers from security firm IOActive.
