Microsoft · Windows Vista · CVE-2008-4038
**Name of the Vulnerable Software and Affected Versions**
Microsoft Windows versions 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008
**Description**
A buffer underflow issue exists in the Server Message Block (SMB) protocol, allowing remote attackers to execute arbitrary code via a crafted filename in an SMB request. The vulnerability can be exploited when the share type is a disk, which by default requires authentication. Successful exploitation could allow an attacker to install programs, view, change, or delete data, or create new accounts with full user rights.
**Recommendations**
For Microsoft Windows 2000 SP4, update to a newer version to mitigate the risk.
For Microsoft Windows XP SP2 and SP3, update to a newer version to mitigate the risk.
For Microsoft Windows Server 2003 SP1 and SP2, update to a newer version to mitigate the risk.
For Microsoft Windows Vista Gold and SP1, update to a newer version to mitigate the risk.
For Microsoft Windows Server 2008, update to a newer version to mitigate the risk.
As a temporary workaround, consider restricting access to disk shares to minimize the risk of exploitation.
