Summary : Utilities for mounting and managing CIFS mounts
Description :
The SMB/CIFS protocol is a standard file sharing protocol widely deployed
on Microsoft Windows machines. This package contains tools for mounting
shares on Linux using the SMB/CIFS protocol. The tools in this package
work in conjunction with support in the kernel to allow one to mount a
SMB/CIFS share onto a client and use it as if it were a standard Linux
file system.

utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs
ip= command-line argument could lead to local attackers gaining root privileges.
