CVE-2017-17310 [High] | Memory Corruption in Dp300 Firmware

Electronic Numbers to URI Mapping (ENUM) module in some Huawei products DP300 V500R002C00, RP200 V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 have a buffer error vulnerability. An unauthenticated, remote attacker has to control the peer device and send specially crafted ENUM packets to the affected products. Due to insufficient verification of some values in the packets, successful exploit may cause buffer error and some services abnormal.
