Title: 'nfs-utils' Package 'hosts_ctl()' Security Bypass Vulnerability
Severity: CRITICAL
Description:
The 'nfs-utils' package provides a daemon for the kernel NFS server and related tools.
The application is prone to a security-bypass vulnerability because of an error in the implementation of TCP wrappers. This issue occurs when a wrong number of arguments are passed to the 'hosts_ctl()' function, causing TCP Wrappers to ignore netgroups.
Remote attackers can exploit this issue to bypass certain security restrictions and gain access to vulnerable computers.
This issue affects 'nfs-utils' 1.0.9; other versions prior to 1.1.3 may also be vulnerable.
