CVE-2020-9565

Code execution via PostScript callothersubr buffer overwrite

Published Jun 26, 2020 · Updated May 5, 2025

Out-of-bounds write in Adobe Bridge 10.0.1 and earlier allows remote attackers to execute code through crafted PostScript content. The callothersubr command handler fails to validate user-supplied data before writing it, causing a write past an allocated buffer. Exploitation requires a user to open a malicious file or visit a malicious page, and resulting code runs in the current process context.
