Stack-based buffer overflow vulnerability exists in multiple laser printers and MFPs which implement Ricoh Web Image Monitor. If this vulnerability is exploited, receiving a specially crafted request created and sent by an attacker may lead to arbitrary code execution and/or a denial-of-service (DoS) condition. As for the details of affected product names and versions, refer to the information provided by the vendors under [References].
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
