Description

A Stack-based Buffer Overflow issue was discovered in WECON LEVI Studio HMI Editor v1.8.1 and prior. Multiple stack-based buffer overflow vulnerabilities have been identified in which the application does not verify string size before copying to memory; the attacker may then be able to crash the application or run arbitrary code.

• CWE-121Stack-based Buffer OverflowA 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).
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
