No reports of the vulnerability being exploited in the wild
Researchers have identified a kernel-level vulnerability in Windows that allows attackers to gain escalated privileges and may also allow them to remotely execute malicious code. All versions of the Microsoft OS are affected, including the heavily fortified Windows 7.
The buffer overflow, which was originally reported here, can be exploited to escalate privileges or crash vulnerable machines, IT research company Vupen said. The flaw may also allow attackers to execute arbitrary code with kernel privileges.
The bug resides in the “CreateDIBPalette()” function of a device driver known as “Win32k.sys.” It is exploited by pasting a large number of color values into an improperly allocated buffer, potentially allowing attackers to sneak in malicious payloads, vulnerability tracking service Secunia warned.
