CVE-2019-5291
Some Huawei products have an insufficient verification of data authenticity vulnerability. A remote, unauthenticated attacker has to intercept specific packets between two devices, modify the packets, and send the modified packets to the peer device. Due to insufficient verification of some fields in the packets, an attacker may exploit the vulnerability to cause the target device to be abnormal.
CVE-2019-5292
Honor 10 Lite, Honor 8A, Huawei Y6 mobile phones with the versions before 9.1.0.217(C00E215R3P1), the versions before 9.1.0.205(C00E97R1P9), the versions before 9.1.0.205(C00E97R2P2) have an information leak vulnerability. Due to improper function error records of some module, an attacker with the access permission may exploit the vulnerability to obtain some information.
CVE-2019-5293
Some Huawei products have a memory leak vulnerability when handling some messages. A remote attacker with operation privilege could exploit the vulnerability by sending specific messages continuously. Successful exploit may cause some service to be abnormal.
CVE-2019-5294
There is an out of bound read vulnerability in some Huawei products. A remote, unauthenticated attacker may send a corrupt or crafted message to the affected products. Due to a buffer read overflow error when parsing the message, successful exploit may cause some service to be abnormal.
CVE-2019-5295
Huawei Honor V10 smartphones versions earlier than Berkeley-AL20 9.0.0.125(C00E125R2P14T8) have an authorization bypass vulnerability. Due to improper authorization implementation logic, attackers can bypass certain authorization scopes of smart phones by performing specific operations. This vulnerability can be exploited to perform operations beyond the scope of authorization.
