CVE-2017-6964

Priority
Medium
Description
dmcrypt-get-device, as shipped in the eject package of Debian and Ubuntu,
does not check the return value of the (1) setuid or (2) setgid function,
which might cause dmcrypt-get-device to execute code, which was intended to
run as an unprivileged user, as root. This affects eject through
2.1.5+deb1+cvs20081104-13.1 on Debian, eject before
2.1.5+deb1+cvs20081104-13.1ubuntu0.16.10.1 on Ubuntu 16.10, eject before
2.1.5+deb1+cvs20081104-13.1ubuntu0.16.04.1 on Ubuntu 16.04 LTS, eject
before 2.1.5+deb1+cvs20081104-13.1ubuntu0.14.04.1 on Ubuntu 14.04 LTS, and
eject before 2.1.5+deb1+cvs20081104-9ubuntu0.1 on Ubuntu 12.04 LTS.
