Description

This security bulletin contains information about 8 vulnerabilities.

1) Information disclosure (CVE-ID: CVE-2017-10268)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local high-privileged attacker to obtain potentially sensitive information on the target system.

The weakness exists due to an error in the MySQL Server component of Oracle MySQL (subcomponent: Server: Replication). A local attacker can gain unauthorized access to critical data or complete access to all MySQL Server accessible data.

Successful exploitation of the vulnerability results in information disclosure.

2) Denial of service (CVE-ID: CVE-2017-10378)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote low-privileged attacker to cause DoS condition on the target system.

The weakness exists due to an error in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). A remote attacker can use multiple protocols to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.

Successful exploitation of the vulnerability results in denial of service.

3) Improper Access Control (CVE-ID: CVE-2018-2562)
