Microsoft Windows NNTP buffer overflow

win-nntp-bo (17641) The risk level is classified as HighHigh Risk

Description:

Microsoft Windows is vulnerable to a buffer overflow in the Network News Transfer Protocol (NNTP) Component, caused by improper bounds checking of user-supplied input. By sending a specially-crafted message to the vulnerable system, a remote attacker could overflow the buffer and execute arbitrary code on the system.

Note: By default, the NNTP component is not installed on Microsoft Windows NT Server 4.0, Windows 2000 Server, and Windows Server 2003, however, some systems that do not use NNTP could still be affected. Some platforms require that the NNTP component be enabled before the platform can be installed, causing the system to be vulnerable.
