CVE Number – CVE-2018-14348
A vulnerability in the libcgroup library could allow a local attacker to access sensitive information on a targeted system.
The vulnerability exists because the cgrulesengd daemon used by the affected software creates the /var/log/cgred file with insecure permissions regardless of umask settings. An attacker could exploit this vulnerability to access sensitive information on a targeted system. A successful exploit could be use to conduct further attacks.
The vendor has confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement may reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to access local systems.
Administrators are advised to allow only privileged users to access administration or management systems.
Administrators are advised to monitor critical systems.
