Description of the vulnerability
The nagios.upgrade_to_v3.sh script is installed by some Linux distributions, in order to migrate Nagios to a recent version.
However, this script uses a predictable filename (/tmp/nagioscfg.$$.tmp) to store the configuration.
When the administrator runs the nagios.upgrade_to_v3.sh script, a local attacker can therefore create a symbolic link, in order to corrupt a file with root privileges.Complete Vigil@nce bulletin....
