Описание
pypdf is a free and open-source pure-python PDF library. Prior to 6.13.1, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires merging a file with threads/articles into a writer. This vulnerability is fixed in 6.13.1.
A flaw was found in pypdf. An attacker can craft a malicious PDF file that, when merged with threads or articles into a writer, can lead to an an infinite loop. This vulnerability can result in a Denial of Service (DoS) condition, making the affected system unresponsive.
Отчет
Red Hat rates this issue as Moderate severity (CVSS 5.9) because exploitation requires a specially crafted PDF containing thread/article objects to be processed by pypdf's merge functionality.
Меры по смягчению последствий
If PDF processing is required, implement processing timeouts and resource constraints (CPU/memory limits) to contain the impact of infinite loops. Running pypdf workloads in containerized processes with enforced resource limits provides defense-in-depth. Upgrading to pypdf >= 6.13.1 resolves this issue.
