Published Aug 20, 2021 · Updated Apr 23, 2025

Out-of-bounds read in Adobe Illustrator 2021 25.2.3 and earlier allows attackers to disclose memory when a victim opens a malicious file. Adobe identifies the flaw as an out-of-bounds read but does not disclose the affected parser, file format, or faulty bounds operation. Opening the crafted file is required; disclosed addresses can weaken ASLR, with no reported data modification or service interruption.
