Code execution via Doc object buffer overwrite
Published Jun 10, 2025 · Updated Jun 10, 2025
Out-of-bounds write in affected Adobe Acrobat Reader releases allows remote attackers to execute code through a malicious file. Doc object handling fails to validate user-supplied data before writing it, allowing data to pass the end of an allocated buffer. Exploitation requires the current user to open the file or visit a malicious page, and resulting code runs in the Reader process context.
