A buffer overflow vulnerability in Microsoft's Pragmatic General Multicast (PGM) protocol implementation may allow an attacker to execute arbitrary code.
A buffer overflow vulnerability exists in the MSMQ service that may allow a remote, unauthenticated attacker to execute arbitrary code. An attacker may be able to send a specially-crafted message that triggers the overflow when received by a vulnerable system.
Per Microsoft, primarily Windows XP is affected by this vulnerability.
A remote, unauthenticated attacker can run arbitrary code with system privileges.
Microsoft has released an update that addresses this issue.
Do not install unnecessary services
The MSMQ service is not installed by default on Windows XP systems. Do not install this service unless multicast support is required.
