Security Advisory - Two Buffer Overflow Vulnerabilities in the GaussDB
- SA No:huawei-sa-20170531-04-gaussdb
- Initial Release Date: 2017-05-31
- Last Release Date: 2017-05-31
There is a buffer overflow vulnerability in the type conversion function of the GaussDB. An attacker logs in to the system as a common user and craft malformed packets, which could be exploited to perform a denial of service attack or possibly remote code execution on the GaussDB. (Vulnerability ID: HWPSIRT-2017-05014)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2014-0064.
There is a buffer overflow vulnerability in the time conversion function of the GaussDB. An attacker logs in to the system as a common user and craft malformed packets. If the length of a specific field is longer than the maximum value, it will be exploited to perform a denial of service attack or possibly remote code execution on the GaussDB. (Vulnerability ID: HWPSIRT-2017-05170)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2014-0063.
