Sensitive-memory disclosure via out-of-bounds read
Published May 11, 2022 · Updated Sep 17, 2024
Out-of-bounds read in Adobe Acrobat Reader DC 22.001.20085 and earlier allows attackers to disclose sensitive memory through a malicious file. Adobe identifies the memory access as an out-of-bounds read but has not published the affected parser, function, or input field read past its valid boundary. A victim must open the file; exploitation discloses process memory and can reveal address-layout data used to bypass ASLR, without reported data modification or code execution.
