Name of the Vulnerable Software and Affected Versions Adobe Animate versions 21.0.9 and earlier

Description The issue is related to a memory corruption vulnerability due to insecure handling of a malicious FLA file, potentially resulting in arbitrary code execution in the context of the current user. This can occur when a user interacts with the malicious file. The vulnerability is also described as a buffer overflow in memory, which can allow an attacker to execute arbitrary code.

Recommendations For Adobe Animate versions 21.0.9 and earlier, update to a version that fixes the memory corruption vulnerability to prevent arbitrary code execution. As a temporary workaround, consider avoiding the use of malicious FLA files and restricting user interaction with untrusted files until a patch is available.
