CVE-2023-48635

Sensitive memory disclosure via malformed AEP parsing

Published Dec 13, 2023 · Updated Sep 11, 2024

Out-of-bounds read in Adobe After Effects 24.0.3 and earlier and 23.6.0 and earlier allows remote attackers to disclose memory via an AEP file. The AEP parser fails to validate user-supplied file data before reading past the end of an allocated buffer. Exploitation requires a victim to open the file or visit a malicious page; disclosure can help bypass ASLR and support a separate code-execution chain.
