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: Services for Unix 2.0 Telnet and NFS Services Contain Memory Leaks Date: 23 July 2001 Software: Services for Unix 2.0 Impact: Denial of service Bulletin: MS01-039 Microsoft encourages customers to review the Security Bulletin at: http://www.microsoft.com/technet/security/bulletin/MS01-039.asp. - ---------------------------------------------------------------------- Issue: ====== Among the components provided by Services for Unix (SFU) 2.0 are services that implement the NFS (Network File System) and Telnet protocols. Both services contain memory leaks that could be triggered by a user request. An attacker who repeatedly sent such a request could deplete the kernel memory on the server to the point where performance slowed and the system could potentially fail. Mitigating Factors: ==================== - Only the implementations provided in SFU 2.0 are affected. In particular, the Telnet services provided in Windows NT(r) 4.0 and Windows(r) 2000 are not affected by the vulnerability. - There is no capability via the vulnerability to usurp any administrative control over the server or compromise any data on it. Patch Availability: =================== - A patch is available to fix this vulnerability. Please read the Security Bulletin http://www.microsoft.com/technet/security/bulletin/ms01-039.asp for information on obtaining this patch.
