Subject: local root exploit confirmed in 2.6.10: Linux 2.6 Kernel Capability LSM Module Local Privilege Elevation
Date: Tue, 28 Dec 2004 16:21:55 -0500 [thread overview]
Message-ID: <1104268915.20714.20.camel@krustophenia.net> (raw)
Frank Barknecht pointed this out on linux-audio-dev, it's a horrible
bug, I confirmed it in 2.6.10, and have not seen it mentioned on the
list.
Executive summary:
run "vim" as normal user. Do ":r /etc/shadow". Permission denied.
do "modprobe capability" as root in another terminal
Do ":r /etc/shadow" again in the same vim. You will be able to read and
write /etc/shadow as normal user.
