Description
This security bulletin contains information about 2 vulnerabilities.
1) Denial of service (CVE-ID: CVE-2017-1433)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.
The weakness exists due to insufficient validation of user-supplied input. A remote attacker can insert messages with a corrupt header into the channel and trigger and cause a server-connection channel process to terminate.
Successful exploitation of the vulnerability results in denial of service.
2) Information disclosure (CVE-ID: CVE-2017-1339)
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 attacker to obtain potentially sensitive information.
The weakness exists due to use of weak encryption for the password. A database administrator can decrypt the client or administrator password to disclose important data or cause DoS condition on the target system.
