Name of the Vulnerable Software and Affected Versions Adobe Bridge versions 10.1.1 and earlier Adobe Bridge versions 11.0.1 and earlier

Description The issue is related to an Out-of-bounds write vulnerability when parsing a crafted file, which could allow an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, specifically that a victim must open a malicious file.

For Adobe Bridge versions 11.0.1 and earlier, update to a version later than 11.0.1 to resolve the issue.
