Background
Apache PDFBox is an open-source Java library for working with PDF documents. It provides functionality for creating, manipulating, and extracting data from PDF files. The library is widely used in various applications and frameworks that deal with PDF documents. However, versions 1.8.0 to 1.8.14 and 2.0.0RC1 to 2.0.10 of Apache PDFBox are vulnerable to an issue that can lead to an infinite loop and an out of memory exception in the AFMParser component.
Vulnerability Detail
The vulnerability in Apache PDFBox arises from a flaw in the AFMParser component. By providing a carefully crafted or fuzzed file, an attacker can trigger an infinite loop with an unreachable exit condition. This can cause the application using Apache PDFBox to consume excessive memory resources, eventually leading to an out of memory exception. The impact of this vulnerability can range from denial of service to potential remote code execution if the application is not properly handling the out of memory exception.
