Sensitive-memory disclosure via out-of-bounds PostScript read
Published Sep 11, 2023 · Updated Aug 4, 2024
Out-of-bounds read in Adobe Acrobat Reader 2019.010.20098 and earlier allows attackers to disclose sensitive memory via a malicious file. The PostScript file parser reads beyond a buffer boundary while processing crafted content; Adobe has not disclosed the responsible function or field. A victim must open the file, after which exposed process memory can reveal address-layout data that assists an ASLR bypass, without reported data modification or service interruption.
