Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2023-5868)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the aggregate function calls when handling "unknown"-type arguments. A remote user can read parts of system memory.
2) Integer overflow (CVE-ID: CVE-2023-5869)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in array modification. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5870)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to pg_cancel_backend rolse signals background workers, including the logical replication launcher, autovacuum workers and the autovacuum launcher. A remote privileged user can abuse this behavior and perform a denial of service (DoS) attack.
4) Improper Privilege Management (CVE-ID: CVE-2024-0985)
The vulnerability allows a remote user to escalate privileges within the database.
The vulnerability exists due to late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY. A remote user who is an object creator can execute arbitrary SQL functions as the command issuer.
5) Improper privilege management (CVE-ID: CVE-2024-10976)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to improper privilege management in cases where a subquery, WITH query, security invoker view, or SQL-language function references a table with a row-level security policy. A remote user can bypass implemented security restrictions and gain unauthorized access to the database in cases where role-specific policies are used and a given query is planned under one role and then executed under other roles.
6) Man-in-the-Middle (MitM) attack (CVE-ID: CVE-2024-10977)
The vulnerability allows a remote attacker to spoof error messages from the database.
The vulnerability exists due to an error in libpq, which allows a server not trusted under current SSL or GSS settings to furnish arbitrary non-NUL bytes to the libpq application. A remote attacker can perform a man-in-the-middle attack to send a long error message that a human or screen-scraper user of psql mistakes for valid query results.
7) Incorrect privilege assignment (CVE-ID: CVE-2024-10978)
The vulnerability allows a remote user to escalate privileges within the application.
The vulnerability exists due to incorrect privilege assignment when application uses SET ROLE, SET SESSION AUTHORIZATION, or an equivalent feature. A remote user can force the application to reset their role to a wrong user ID and view or change different rows from those intended.
8) Improper authorization (CVE-ID: CVE-2024-10979)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to incorrect control of environment variables. A remote unprivileged database user can change sensitive process environment variables (e.g. PATH) and execute arbitrary code on the database server.
9) Security features bypass (CVE-ID: CVE-2023-2455)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.
This affects only databases that have used CREATE POLICY to define a row security policy.
10) Security Features (CVE-ID: CVE-2016-2193)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
PostgreSQL before 9.5.x before 9.5.2 does not properly maintain row-security status in cached plans, which might allow attackers to bypass intended access restrictions by leveraging a session that performs queries as more than one role.
