漏洞描述

中文描述:

grub2是GNU社区的一款Linux系统引导程序。 GRUB2 2.04及之前版本中的efilinux组件的‘grub_cmd_initrd’和‘grub_initrd_init’函数存在输入验证错误漏洞。攻击者可利用该漏洞执行任意代码并绕过UEFI安全启动限制。

英文描述:

Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
