This security bulletin contains information about 5 vulnerabilities.


1) Buffer Over-read (CVE-ID: CVE-2025-4207)

CWE-ID: CWE-126 - Buffer over-read

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a buffer over-read in GB18030 encoding validation. A remote attacker can pass specially crafted input to the application, trigger a one-byte buffer over-read and perform a denial of service (DoS) attack.


2) Code Injection (CVE-ID: CVE-2025-8714)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary psql code on the target system.

The vulnerability exists due to improper input validation in pg_dump. A malicious superuser of the origin server to inject arbitrary psql code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands, such as pg_dump, pg_dumpall, and pg_restore.


3) Improper input validation (CVE-ID: CVE-2024-21096)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 2.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local non-authenticated attacker to read and manipulate data.

The vulnerability exists due to improper input validation within the Client: mysqldump component in MySQL Server. A local non-authenticated attacker can exploit this vulnerability to read and manipulate data.


4) Input validation error (CVE-ID: CVE-2025-8715)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary psql code.

The vulnerability exists in pg_dump due to insufficient validation of user-supplied input when handling new line characters. A remote attacker can trick the victim into loading a specially crafted backup and execute arbitrary psql code on the system.


5) SQL injection (CVE-ID: CVE-2012-0868)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

CRLF injection vulnerability in pg_dump in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 allows user-assisted remote attackers to execute arbitrary SQL commands via a crafted file containing object names with newlines, which are inserted into an SQL script that is used when the database is restored.
