Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Data handling (CVE-ID: CVE-2017-15098)
The vulnerability allows a remote authenticated attacker to cause DoS condition or obtain potentially sensitive information on a targeted system.The weakness exists due to improper data handling. A remote attacker can send specially crafted data to trigger a rowtype mismatch in json{b}_populate_recordset(), cause the application to crash or read arbitrary data.
2) Security restrictions bypass (CVE-ID: CVE-2017-15099)
The vulnerability allows a remote attacker to bypass security restrictions on a targeted system.The weakness exists due to improper security restrictions in the case of an arbiter specified by constraint name. A remote attacker can submit specially crafted INSERT requests and bypass security controls on the update path of 'INSERT ... ON CONFLICT DO UPDATE' function to conduct further attacks.
3) Information disclosure (CVE-ID: CVE-2018-1053)
A vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.The vulnerability exists due to insufficient security restrictions. A remote attacker can gain access to sensitive information.
4) Privilege escalation (CVE-ID: CVE-2018-1058)
The vulnerability allows a local attacker to gain elevated privileges on the target system.The weakness exists in the pg_dump function due to improper security restrictions. A local attacker can submit a malicious function in separate namespaces and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
5) Security restrictions bypass (CVE-ID: CVE-2018-1115)
The vulnerability allows a remote authenticated attacker to bypass security restrictions on the target system.The weakness exists in the pg_catalog.pg_logfile_rotate() function due to improper Access Control List (ACL) restrictions as it does not follow the same ACLs as the pg_rorate_logfile function. A remote attacker can connect to the database and cause the target software to force log rotation, write log messages across arbitrary log files or cause the service to crash.
6) SQL injection (CVE-ID: CVE-2018-10915)
The vulnerability allows a remote attacker to execute arbitrary SQL commands in web application database.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can send a specially crafted HTTP request to vulnerable script and execute arbitrary SQL commands in web application database.
Successful exploitation of the vulnerability may allow an attacker to gain administrative access to vulnerable web application.
7) Information disclosure (CVE-ID: CVE-2018-10925)
The vulnerability allows a remote privileged attacker to obtain potentially sensitive information.
The vulnerability exists due to improper check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". A remote attacker with "CREATE TABLE" privileges can read arbitrary bytes server memory.
