CVE-2023-22227

Code execution via embedded-font buffer overrun

Published Feb 17, 2023 · Updated Mar 5, 2025

Out-of-bounds write in Adobe Bridge 12.0.3 and earlier and 13.0.1 and earlier allows remote attackers to execute code via a malicious file. Embedded-font processing writes crafted font data past the end of an allocated buffer. Execution requires a victim to visit a malicious page or open the file, and the resulting code runs in the context of the current process.
