Name of the Vulnerable Software and Affected Versions
Acrobat Bridge versions 11.1.1 and earlier
Adobe Media Encoder version 15.4 and earlier
Description
The issue is related to a use-after-free vulnerability in the processing of Format event actions and a memory corruption vulnerability that could result in 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, such as a malicious M4A file.
Recommendations
For Acrobat Bridge versions 11.1.1 and earlier, update to a version later than 11.1.1 to resolve the issue.
For Adobe Media Encoder version 15.4 and earlier, update to a version later than 15.4 to resolve the issue.
As a temporary workaround, consider avoiding the use of the Format event actions feature in Acrobat Bridge and restricting the opening of M4A files in Adobe Media Encoder until a patch is available.
Fix
