There is a memory leak vulnerability in CloudEngine 12800 V200R019C00SPC800, CloudEngine 5800 V200R019C00SPC800, CloudEngine 6800 V200R019C00SPC800 and CloudEngine 7800 V200R019C00SPC800. The software does not sufficiently track and release allocated memory while parse a series of crafted binary messages, which could consume remaining memory. Successful exploit could cause memory exhaust.
