Background
PostgreSQL is an object-relational SQL database that provides a robust and scalable solution for managing data. It offers advanced features such as support for complex queries, indexing, and transaction management. However, several local vulnerabilities have been discovered in PostgreSQL version 7.4.
Vulnerability Detail
The Common Vulnerabilities and Exposures project has identified multiple vulnerabilities in PostgreSQL 7.4:
-
CVE-2007-3278: The DBLink module in PostgreSQL performed insufficient credential validation, potentially leading to unauthorized access.
-
CVE-2007-4769: A bug in the handling of back-references inside the regular expressions engine could result in an out-of-bounds read, leading to a crash. This vulnerability is only exploitable if an application processes regular expressions from untrusted sources.
-
CVE-2007-4772: The optimizer for regular expressions in PostgreSQL could be tricked into an infinite loop, causing a denial of service. This vulnerability is only exploitable if an application processes regular expressions from untrusted sources.
-
CVE-2007-6067: The optimizer for regular expressions in PostgreSQL could be manipulated to consume excessive resources, potentially leading to a denial of service. This vulnerability is only exploitable if an application processes regular expressions from untrusted sources.
-
CVE-2007-6600: Functions in index expressions could be abused to escalate privileges.
These vulnerabilities pose a risk to systems running PostgreSQL 7.4, especially if they process regular expressions from untrusted sources or utilize index expressions.
