Background
PostgreSQL is an advanced object-relational database management system (DBMS) that provides robust data storage and retrieval capabilities. It is widely used in various applications and industries for managing large volumes of structured data. PostgreSQL offers a range of features, including support for complex queries, transactional integrity, and extensibility through user-defined functions and data types. However, like any software, PostgreSQL is susceptible to security vulnerabilities that can compromise the confidentiality, integrity, and availability of data stored in the database.
Vulnerability Detail

This vulnerability allows an attacker to overwrite adjacent memory locations, potentially leading to arbitrary code execution or denial of service. The impact of this vulnerability depends on the specific usage scenario and the privileges of the attacker. It is rated as important due to the potential for remote code execution and the potential impact on the confidentiality and integrity of data.
How To Fix
