Huawei CloudEngine 12800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 5800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 6800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 7800 V100R003C00, V100R005C00, V100R005C10, V100R006C00 have a memory leak vulnerability. An unauthenticated attacker may send specific Resource ReServation Protocol (RSVP) packets to the affected products. Due to not release the memory to handle the packets, successful exploit will result in memory leak of the affected products and lead to a DoS condition.

Common Attack Pattern Enumeration and Classification (CAPEC)
- HTTP DoS An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
