Description

A Stack-based Buffer Overflow issue was discovered in GE CIMPLICITY Versions 9.0 and prior. A function reads a packet to indicate the next packet length. The next packet length is not verified, allowing a buffer overwrite that could lead to an arbitrary remote code execution.

• 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.
