Huawei Data Communication: Several Vulnerabilities in XMLparser Module of Huawei Products (huawei-sa-20180418-01-xmlparser)

There are two memory leak vulnerabilities in XMLparser module of Huawei products.

There are two memory leak vulnerabilities in XMLparser module of Huawei products. The vulnerability is due to incorrect handling of parameters. A local attacker could exploit this vulnerability by sending crafted parameters. A successful exploit could cause a memory leak and eventual denial of service (DoS) condition on an affected device. (Vulnerability ID: HWPSIRT-2017-04029 and HWPSIRT-2017-08243)There is a denial of service (DoS) vulnerability in XMLparser module of Huawei products. The vulnerability is due to lack of validation in XML document. A local attacker could exploit this vulnerability by crafting a malicious XML document. A successful exploit by the attacker could lead to resource exhaust and cause a DoS condition. (Vulnerability ID: HWPSIRT-2017-04030)There is a null pointer dereference vulnerability in XMLparser module of Huawei products. When the application dereferences a pointer that it expects to be valid, but is NULL. A local attacker could exploit this vulnerability by sending crafted parameters. A successful exploit could cause a denial of service and the process reboot. (Vulnerability ID: HWPSIRT-2017-04031)There are four out-of-bounds read vulnerabilities in XMLparser module of Huawei products. A local attacker may send crafted parameters in XML document to the affected products. Due to insufficient verification of the parameter, successful exploit will cause a DoS condition and the process reboot. (Vulnerability ID: HWPSIRT-2017-04032,HWPSIRT-2017-04074,HWPSIRT-2017-08244 and HWPSIRT-2017-08245)Huawei has released software updates to fix these vulnerabilities. This advisory is available in the linked references.
