Multiple heap-based buffer overflow vulnerabilities exist in Honeywell Experion PKS all versions prior to R400.6, all versions prior to R410.6, and all versions prior to R430.2 modules, which could lead to possible remote code execution or denial of service. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The 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.
