Vulnerabilities for 'Postgresql'

CVE-2023-5868

CWE-noinfo

A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.

CVE-2023-5869

CWE-190

A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.

CVE-2023-5870

CWE-noinfo

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.

CVE-2022-24844

CWE-89

Gin-vue-admin is a backstage management system based on vue and gin, which separates the front and rear of the full stack. The problem occurs in the following code in server/service/system/sys_auto_code_pgsql.go, which means that PostgreSQL must be used as the database for this vulnerability to occur. Users must: Require JWT login? and be using PostgreSQL to be affected. This issue has been resolved in version 2.5.1. There are no known workarounds.

CVE-2021-23222

CWE-522

A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption.

CVE-2021-3677

NVD-CWE-noinfo

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.

CVE-2021-32028

CWE-200

A flaw was found in postgresql. Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality.

2021-10-08

CVE-2021-32029

NVD-CWE-noinfo

A flaw was found in postgresql. Using an UPDATE ... RETURNING command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality.

2021-04-01

CVE-2021-3393

CWE-209

An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.

2021-02-23

CVE-2021-20229

CWE-863

A flaw was found in PostgreSQL in versions before 13.2, before 12.6, before 11.11, before 10.16, before 9.6.21 and before 9.5.25. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality.
