Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) SQL injection (CVE-ID: CVE-2020-25695)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote authenticated attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-10208)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to way PostreSQL processes SECURITY DEFINER functions. A privileged attacker with EXECUTE permission, which must itself contain a function call having inexact argument type match, can execute arbitrary SQL query under the identity of the function owner.
3) Stack-based buffer overflow (CVE-ID: CVE-2019-10164)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing users passwords. A remote authenticated user can change his/her password to a specially crafted string, trigger stack-based buffer overflow and execute arbitrary code on the target system or crash the PostgreSQL process.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Input validation error (CVE-ID: CVE-2020-25696)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the "\gset" meta-command does not distinguish variables that control psql behavior. A remote attacker can execute arbitrary code as the operating system account.
5) Untrusted search path (CVE-ID: CVE-2020-14350)
The vulnerability allows a remote user to escalate privileges within the database.
The vulnerability exists due to the way PostgreSQL handles CREATE EXTENSION statements. A remote user with permission to create objects in the new extension's schema
or a schema of a prerequisite extension can execute arbitrary SQL functions under the identity of the superuser in certain cases.
6) Untrusted search path (CVE-ID: CVE-2020-14349)
The vulnerability allows a remote user to escalate privileges within the database.
The vulnerability exists due to the way PostgreSQL handles search_path during replications. Users of a
replication publisher or subscriber database can create objects in the public
schema and harness them to execute arbitrary SQL functions under the identity
running replication, often a superuser.
