CVE-2020-9562

Code execution via malformed PCX file parsing

Published Jun 26, 2020 · Updated May 5, 2025

Heap overflow in Adobe Bridge 10.0.1 and earlier allows remote attackers to execute arbitrary code by opening a crafted PCX file. The PCX parser copies user-supplied data into a heap buffer without first validating its length. Exploitation requires the current user to visit a malicious page or open a malicious file, and resulting code runs in the Bridge process context.
