Memory disclosure via embedded-font out-of-bounds read
Published Aug 10, 2023 · Updated Feb 27, 2025
Out-of-bounds read in Adobe Acrobat Reader 23.003.20244 and earlier allows remote attackers to disclose memory through a malicious PDF. The embedded-font parser fails to validate user-supplied font data before reading past an allocated object. A victim must visit a malicious page or open a malicious file; the disclosure can expose process memory and help bypass ASLR.
