CVE-2022-24960

Code execution via crafted PDF use-after-free

Published Mar 9, 2022 · Updated Sep 17, 2024

Use-after-free in PDFTron SDK 9.2.0 allows attackers to control execution by opening a crafted PDF on Linux, macOS, or Windows. PDF parsing reuses a freed heap allocation, allowing document content to overwrite the RIP instruction pointer with heap-controlled data. Exploitation requires user interaction with the file and can corrupt memory, disclose data, or execute code in the affected process.
