Name of the Vulnerable Software and Affected Versions Adobe Media Encoder versions 22.0, 15.4.2 and earlier

Description The issue is related to an out-of-bounds read vulnerability in Adobe Media Encoder that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction, where a victim must open a malicious MP4 file. This could potentially allow a remote attacker to gain unauthorized access to protected information using a specially crafted MP4 file.

Recommendations For Adobe Media Encoder versions 22.0, 15.4.2 and earlier, consider avoiding the use of MP4 files from untrusted sources until a patch is available. As a temporary workaround, consider restricting the ability to open MP4 files in Adobe Media Encoder to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
