Name of the Vulnerable Software and Affected Versions Adobe Media Encoder versions 15.2 and earlier

Description The issue is caused by a buffer overflow when parsing a specially crafted file, potentially allowing a remote attacker to execute arbitrary code. An unauthenticated attacker could leverage this vulnerability to achieve arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, where a victim must open a malicious file.

Recommendations For Adobe Media Encoder versions 15.2 and earlier, update to a version that is not affected by this issue.
