Description Vasyl Kaigorodov 2014-05-16 13:13:35 UTC

It was reported [1] that check_dhcp plugin allow local unprivileged user to read parts of INI
config files belonging to root on a local system. It could allow an attacker to obtain sensitive information like passwords that should only be accessible by root user.
The vulnerability is due to check_dhcp plugin having Root SUID permissions and inappropriate access control when reading user provided config file (through --extra-opts= option).

This was fixed in version 2.0.2; however, a race condition was discovered that, even with the patch, allowed root owned files to be read:
