Talos is disclosing the presence of two vulnerabilities in the Artifex MuPDF renderer. MuPDF is a lightweight PDF parsing and rendering library featuring high fidelity graphics, high speed, and compact code size which makes it a fairly popular PDF library for embedding in different projects, especially mobile and web applications. Both of these vulnerabilities, if exploited, could lead to arbitrary code execution of an attacker’s choice on the target device. Both of these vulnerabilities have been responsibly disclosed and Artifex has released software updates to address these vulnerabilities.
Two memory corruption vulnerabilities exist within Artifex MuPDF render that could result in arbitrary code execution if exploited. These two vulnerabilities manifest as a result of improperly parsing and handling parts of a PDF file.
