CVE-2018-14665:setuid 複寫檔案的 security issue...

Twitter 上看到的 security issue,好久沒在這麼普及的軟體上看到這種 bug 了:

CVE - CVE-2018-14665 的說明裡面有提到 1.20.3 前的版本都有中,但沒講到從哪個版本開始,看起來是全系列...?

A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
