Cisco Talos recently discovered a vulnerability in the Nitro Pro PDF reader that could allow an attacker to execute code in the context of the application.
Nitro Pro PDF is part of Nitro Software’s Productivity Suite. Pro PDF allows users to create and modify PDFs and other digital documents. It includes support for several capabilities via third-party libraries to parse the PDFs.
TALOS-2021-1267 (CVE-2021-21798) is a use-after-free vulnerability that can be triggered if a target opens a specially crafted, malicious PDF.
Cisco Talos worked with Nitro to ensure that these issues are resolved and an update is available for affected customers, all in adherence to Cisco’s vulnerability disclosure policy.
