Description

Huawei DP300 V500R002C00, TE60 V600R006C00, TP3106 V100R002C00, eSpace U1981 V200R003C30SPC100 have a denial of service vulnerability. The software does not correctly calculate the rest size in a buffer when handling SSL connections. A remote unauthenticated attacker could send a lot of crafted SSL messages to the device, successful exploit could cause no space in the buffer and then denial of service.
