Security Advisory - Three Vulnerabilities in Huawei GaussDB
- SA No:huawei-sa-20171025-01-gaussdb
- Initial Release Date: Oct 25, 2017
- Last Release Date: Nov 10, 2017
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-10195.
There is a DoS vulnerability in libevent of Huawei GaussDB. Due to insufficient input validation, a remote attacker could exploit this vulnerability by causing an application using libevent to parse a malformed IPv6 address. Successful exploit of the vulnerability could cause stack overflow and cause a crash. (Vulnerability ID: HWPSIRT-2017-05048)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-10196.
There is an out-of-bounds read vulnerability in libevent of Huawei GaussDB. Due to insufficient input validation, a remote attacker could exploit this vulnerability by causing an application using libevent to attempt resolving an empty hostname. Successful exploit of the vulnerability could cause out-of-bounds read and possibly cause a crash. (Vulnerability ID: HWPSIRT-2017-05049)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-10197.
