There is a few bytes out-of-bounds read vulnerability in some Huawei products. The software reads data past the end of the intended buffer when parsing certain message, an authenticated attacker could exploit this vulnerability by sending crafted messages to the device. Successful exploit may cause service abnormal in specific scenario.Affected product versions include:AR120-S versions V200R007C00SPC900,V200R007C00SPCa00

Huawei AR100, AR100-S, AR110-S, AR120, AR120-S, AR1200, AR1200-S, AR150, AR150-S, AR160, AR200, AR200-S, AR2200, AR2200-S, AR3200, AR510, DP300, NetEngine16EX, RP200, SRG1300, SRG2300, SRG3300, TE30, TE40, TE50, TE60, TP3106, TP3206, ViewPoint 8660, and ViewPoint 9030 have an insufficient validation vulnerability. Since packet validation is insufficient, an unauthenticated attacker may send special H323 packets to exploit the vulnerability. Successful exploit could allow the attacker to send malicious packets and result in DOS attacks.
