[原文]Sendmail before 8.12.1 does not properly drop privileges when the -C option is used to load custom configuration files, which allows local users to gain privileges via malformed arguments in the configuration file whose names contain characters with the high bit set, such as (1) macro names that are one character long, (2) a variable setting which is processed by the setoption function, or (3) a Modifiers setting which is processed by the getmodifiers function.


[CNNVD]Sendmail不充分特权降低漏洞(CNNVD-200110-122)

        Sendmail 8.12.1之前版本在-C选项用于载入自定义配置文件时不能正确地降低特权,本地用户可以借助名称中含高位设置(例如:(1)宏名称为一字符长,(2)被setoption函数处理的变量设置,或(3)被getmodifiers函数处理的Modifiers设置)字符的配置文件中畸形参数提升特权。

- 漏洞讨论

Sendmail is a widely used MTA often shipped with Unix systems.

In version 8.12.0, the 'sendmail' utility is setgid instead of setuid. The code that drops privileges does not lower the saved groupid. It is therefore possible to reclaim the effective groupid if an attacker can force the process to call setregid(). This may be possible due to several bugs in the config file parser.
