Security Advisory - Two Out-of-Bounds Read Vulnerabilities in Some Huawei Products

  • SA No:huawei-sa-20180207-03-h323
  • Initial Release Date: Feb 07, 2018
  • Last Release Date: Feb 07, 2018

Some Huawei products have two out-of-bounds read vulnerabilities due to the improper processing of malformed H323 messages. A remote attacker that controls a server could exploit this vulnerability by sending malformed H323 reply messages to a target device. Successful exploit could make the device read out of bounds and probably make a service unavailable. (Vulnerability ID: HWPSIRT-2017-08046 and HWPSIRT-2017-08047)
The two vulnerabilities have been assigned two Common Vulnerabilities and Exposures (CVE) IDs: CVE-2017-17199 and CVE-2017-17200.
Huawei has released software updates to fix these vulnerabilities. This advisory is available at the following link:
