CVE-2022-34260

Code execution via embedded-font out-of-bounds write

Published Aug 11, 2022 · Updated Apr 23, 2025

Out-of-bounds write in Adobe Illustrator 26.3.1 and earlier and 25.4.6 and earlier allows remote attackers to execute code via a malicious file. The embedded-font parser writes crafted font data past the end of an allocated buffer. Exploitation requires a user to open the file or visit a page that supplies it, and resulting code runs in the context of the current Illustrator process.
