Background
SQLite3 is a widely used database engine that provides a lightweight, serverless, self-contained SQL database. It is commonly utilized in various applications for data storage and management due to its simplicity and efficiency. However, the SQLite3 package version 3.45.1-1ubuntu2.3 has been identified to contain a critical vulnerability that can lead to severe security risks.
Vulnerability Detail
The vulnerability arises from an integer overflow in SQLite's concat_ws() function. When this function is invoked, it can produce a truncated integer that is subsequently used to allocate a buffer. This leads to a wild Heap Buffer overflow of approximately 4GB when SQLite attempts to write the resulting string to the buffer using the original, untruncated size. This overflow can potentially allow an attacker to execute arbitrary code, posing a significant threat to system integrity and security.
How To Fix
Minimum fixed version
3.45.1-1ubuntu2.3
