The following is a Security Bulletin from the Microsoft Product Security Notification Service. Please do not reply to this message, as it was sent from an unattended mailbox. ******************************** -----BEGIN PGP SIGNED MESSAGE----- - ---------------------------------------------------------------------- Title: NNTP Service in Windows NT 4.0 and Windows 2000 Contains Memory Leak Date: 14 August 2001 Software: Windows NT 4.0, Windows 2000 Impact: Denial of service Bulletin: MS01-043 Microsoft encourages customers to review the Security Bulletin at: http://www.microsoft.com/technet/security/bulletin/MS01-043.asp. - ---------------------------------------------------------------------- Issue: ====== The NNTP (Network News Transport Protocol) service in Windows NT 4.0 and Windows 2000 contains a memory leak in a routine that processes news postings. Each time such a posting is processed that contains a particular construction, the memory leak causes a small amount of memory to no longer be available for use. If an attacker sent a large number of posts, the server memory could be depleted to the point at which normal service would be disrupted. An affected server could be restored to normal service by rebooting. Mitigating Factors: ==================== - Windows NT 4.0 does not contain a native NNTP service. NNTP is only available on the system if the Windows NT 4.0 Option Pack has been installed. - The default configuration of NNTP is not affected by the vulnerability, as no newsgroups are configured by default. - The vulnerability would not enable an attacker to usurp any administrative control or compromise data on the machine. Patch Availability: =================== - A patch is available to fix this vulnerability. Please read the Security Bulletin http://www.microsoft.com/technet/security/bulletin/ms01-043.asp for information on obtaining this patch.
