Security firm Secunia warned Thursday of a new flaw within Windows XP and Windows Server 2003 that could cause a denial of service issue. The vulnerability can be exploited to cause a buffer overflow, which in turn would cause Windows to crash. Labeled as a "less critical" vulnerability, the flaw could be used to execute arbitrary code, but Secunia was unable to prove that in tests.

Microsoft said that it was investigating the issue, however was not aware of any attack vectors that attempt to exploit the problem. "The vulnerability has been confirmed on a fully patched system with Microsoft Windows XP SP2 and Microsoft Windows 2003 Server," Secunia wrote in its advisory. It is unclear if Microsoft plans to address the flaw on its next Patch Tuesday, scheduled for June 13.
