An exploitable double-free vulnerability exists in the JavaScript implementation of Nitro Pro PDF. A specially crafted document can cause a reference to a timeout object to be stored in two different places. When closed, the document will result in the reference being released twice. This can lead to code execution under the context of the application. An attacker can convince a user to open a document to trigger this vulnerability. • https://talosintelligence.com/vulnerability_reports/TALOS-2021-1266 • CWE-415: Double Free •

An exploitable use-after-free vulnerability exists in the JavaScript implementation of Nitro Pro PDF. A specially crafted document can cause an object containing the path to a document to be destroyed and then later reused, resulting in a use-after-free vulnerability, which can lead to code execution under the context of the application. An attacker can convince a user to open a document to trigger this vulnerability. Se presenta una vulnerabilidad explotable de uso de memoria previamente liberada en la implementación de JavaScript de Nitro Pro PDF. Un documento especialmente diseñado puede causar la destrucción de un objeto que contiene la ruta de acceso a un documento y su posterior reuso, resultando en una vulnerabilidad de uso de memoria previamente liberada, que puede conllevar a una ejecución de código bajo el contexto de la aplicación. • https://talosintelligence.com/vulnerability_reports/TALOS-2021-1265 • CWE-416: Use After Free •

An exploitable return of stack variable address vulnerability exists in the JavaScript implementation of Nitro Pro PDF. A specially crafted document can cause a stack variable to go out of scope, resulting in the application dereferencing a stale pointer. This can lead to code execution under the context of the application. An attacker can convince a user to open a document to trigger the vulnerability. Se presenta una vulnerabilidad explotable de retorno de dirección de variable de pila en la implementación de JavaScript de Nitro Pro PDF. • https://talosintelligence.com/vulnerability_reports/TALOS-2021-1267 • CWE-562: Return of Stack Variable Address •

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, a Signature Wrapping vulnerability exists in multiple products. An attacker can use /ByteRange and xref manipulations that are not detected by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects eXpert PDF 12 Ultimate, Expert PDF Reader, Nitro Pro, Nitro Reader, PDF Architect 6, PDF Editor 6 Pro, PDF Experte 9 Ultimate, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, PDF-XChange Editor and Viewer, Perfect PDF 10 Premium, Perfect PDF Reader, Soda PDF, and Soda PDF Desktop. • https://pdf-insecurity.org/signature/evaluation_2018.html https://pdf-insecurity.org/signature/signature.html https://www.foxitsoftware.com/support/security-bulletins.php https://www.pdfa.org/recently-identified-pdf-digital-signature-vulnerabilities • CWE-347: Improper Verification of Cryptographic Signature •

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader. • https://pdf-insecurity.org/signature/evaluation_2018.html https://pdf-insecurity.org/signature/signature.html https://www.foxitsoftware.com/support/security-bulletins.php https://www.pdfa.org/recently-identified-pdf-digital-signature-vulnerabilities • CWE-347: Improper Verification of Cryptographic Signature •
