[原文]An error in the Toshiba ACPI BIOS 1.6 causes the BIOS to only examine the first slot in the Master Boot Record (MBR) table for an active partition, which prevents the system from booting even though the MBR is not malformed. NOTE: it has been debated as to whether or not this issue poses a security vulnerability, since administrative privileges would be required, and other DoS attacks are possible with such privileges.


[CNNVD]Toshiba ACPI BIOS 漏洞(CNNVD-200505-763)

        Toshiba ACPI BIOS 1.6中的一个错误使得BIOS只检查活动分区中Master Boot Record (MBR) 表的第一个槽位 ,这阻止了系统的引导,即便MBR是正常的。注:此问题是否为安全漏洞有争议,因为这需要管理员权限,并且其他DoS攻击可能由此权限。

Toshiba ACPI BIOS MBR Boot Order Issue
Physical Access Required Denial of Service
Loss of Availability
Exploit Unknown

- 漏洞描述

Toshiba ACPI BIOS contains a flaw that may allow a local denial of service. The issue is due to an error, which causes the BIOS to only check the first slot in the MBR table for a bootable partition. It is possible for a malicious user to arbitrary specify a different slot in the MBR table, which prevents the system from booting resulting in a loss of availability.
