Descriptions

Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, and Office 2007 SP3, when IMJPDCT.EXE (aka IME for Japanese) is installed, allow remote attackers to bypass a sandbox protection mechanism via a crafted PDF document, aka "Microsoft IME (Japanese) Elevation of Privilege Vulnerability," as exploited in the wild in 2014.

Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, y Office 2007 SP3, cuando IMJPDCT.EXE (también conocido como IME para japonés) está instalado, permiten a atacantes remotos evadir un mecanismo de protección sandbox a través de un documento PDF manipulado, también conocido como 'vulnerabilidad de la elevación de privilegios de Microsoft IME (japonés),' tal y como fue utilizado activamente en 2014.

Microsoft Input Method Editor (IME) Japanese is a keyboard with Japanese characters that can be enabled on Windows systems as it is included by default (with the default set as disabled). IME Japanese contains an unspecified vulnerability when IMJPDCT.EXE (IME for Japanese) is installed which allows attackers to bypass a sandbox and perform privilege escalation.
