The remote Windows host has an application that is affected by a local format string vulnerability.


The version of Symantec pcAnywhere installed on the remote Windows host does not properly handle format strings within remote control file names ('.CHF') or their associated file paths. Using a specially crafted file or path name, a local user may be able to exploit this issue to read or write arbitrary memory and at a minimum crash the affected application.


Upgrade to pcAnywhere version 12.5.0 Build 442 (also known as 12.5 SP1) or later.
