Details have emerged about a high severity security vulnerability affecting a software driver used in HP, Xerox, and Samsung printers that has remained undetected since 2005.
Tracked as CVE-2021-3438 (CVSS score: 8.8), the issue concerns a buffer overflow in a print driver installer package named “SSPORT.SYS” that can enable remote privilege and arbitrary code execution. Hundreds of millions of printers have been released worldwide to date with the vulnerable driver in question.
However, there is no evidence that the flaw was abused in real-world attacks.
