Vulnerability Information

Kernel Race Condition Vulnerability - CVE-2013-1278

An elevation of privilege vulnerability exists when the Windows kernel 
improperly handles objects in memory. An attacker who successfully exploited
this vulnerability could run arbitrary code in kernel mode. An attacker could
then install programs; view, change, or delete data; or create new accounts
with full administrative rights.

Kernel Race Condition Vulnerability - CVE-2013-1279
