Sudo是一款使用于类Unix系统的，允许用户通过安全的方式使用特殊的权限执行命令的程序。 1.9.12p2 之前的 Sudo存在安全漏洞，该漏洞源于sudoedit（又名 -e）功能错误处理用户提供的环境变量（SUDO_EDITOR、VISUAL 和 EDITOR）中传递的额外参数，从而允许本地攻击者将任意条目附加到要处理的文件列表中 . 这可能导致特权升级。

Vulnerability Title

Source: CVE Program / CVE List V5
Vulnerability Description
In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value.
