CVE-2017-17282 [Low] | Memory Corruption in Dp300 Firmware

SCCP (Signalling Connection Control Part) module in Huawei DP300 V500R002C00, RP200 V500R002C00, V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 has a buffer overflow vulnerability. An attacker has to find a way to send malformed packets to the affected products repeatedly. Due to insufficient input validation, successful exploit may cause some service abnormal.
