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 a memory corruption vulnerability when parsing a specially crafted file. This can allow an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file.

Recommendations For Adobe Bridge versions 10.1.1 and earlier, update to a version later than 10.1.1 to resolve the issue. For Adobe Bridge versions 11.0.1 and earlier, update to a version later than 11.0.1 to resolve the issue. As a temporary workaround, consider avoiding the use of the file parsing functionality until a patch is available.
