Microsoft is investigating a report issued by FireEye Labs that warned of a local privilege escalation zero-day exploit in a kernel module of Windows XP and Windows Server 2003.

According to the software major, the Microsoft Windows Kernel ‘NDProxy.sys’ Local Privilege Escalation Vulnerability (CVE-2013-5065) would let hackers to run arbitrary code in kernel-level.

Hackers can then install programmes, as well view, change, or delete data or create new accounts with complete administrative rights, which would completely compromise affected PCs.

Security firm Symantec revealed that attacks have been carried out from the beginning of November, and they arrive as a malicious PDF file with file names including syria15.10.pdf or Note_?107-41D.pdf, probably by an email attachment.

Microsoft suggests users to upgrade to the latest Adobe Reader, as well as upgrade to Microsoft Windows 7 or higher in a bid to protect from the in-the-wild PDF exploit.

Last week, Microsoft rolled out a patch to deal with issues related to Exchange Server 2013 that hit its backup and recovery operations.
