Name of the Vulnerable Software and Affected Versions Adobe Prelude versions 10.1 and earlier

Description The issue is related to a memory corruption vulnerability that could allow an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. Exploitation requires user interaction, specifically opening a malicious M4A file. This vulnerability is associated with a buffer overflow in memory, which can be leveraged by an attacker to execute arbitrary code.

Recommendations For Adobe Prelude versions 10.1 and earlier, consider avoiding the use of M4A files from untrusted sources until a patch is available. As a temporary workaround, restrict the ability to open M4A files in Adobe Prelude to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
