漏洞描述
中文描述:
Bash是美国布莱恩-福克斯（Brian J. Fox）个人开发者的一款为GNU计划而编写的、运行于类Unix操作系统中的Shell（命令语言解释器）。它能够从标准输入设备或文件中读取、执行命令。 Bash 5.0 patch 11及之前版本中的shell.c文件的disable_priv_mode存在安全漏洞。攻击者可利用该漏洞获取权限。
英文描述:
An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected.
