Code execution via Annotation object out-of-bounds write
Published Jan 27, 2023 · Updated Mar 5, 2025
Out-of-bounds write in Adobe Acrobat Reader 22.003.20282 and earlier allows remote attackers to execute code through a malicious PDF. JavaScript actions on an AcroForm Annotation object drive the parser to write past the end of the object's allocated memory. The victim must open the crafted file or visit a malicious page, after which code runs in the current process and user context.
