107 | <para><command>make install</command>: Installs <command>traceroute</command>
|
---|
108 | with SUID set to <systemitem class="username">root</systemitem> in the
|
---|
109 | <filename class='directory'>/usr/sbin</filename> directory. This makes it
|
---|
110 | possible for all users to execute <command>traceroute</command>. For absolute
|
---|
111 | security, turn off the SUID bit in <command>traceroute</command>'s file permissions
|
---|
112 | with the command:</para>
|
---|
113 |
|

114 | <screen role='root'><userinput>chmod -v 0755 /usr/sbin/traceroute</userinput></screen>
|

115 |
|
---|
116 | <para>The risk is that if a security problem such as a buffer overflow was
|
---|
117 | ever found in the <application>Traceroute</application> code, a regular user
|
---|
118 | on your system could gain <systemitem class="username">root</systemitem>
|
---|
119 | access if the program is SUID <systemitem class="username">root</systemitem>.
|
---|
120 | Of course, removing the SUID permission also makes it impossible for users other
|
---|
121 | than <systemitem class="username">root</systemitem> to utilize
|
---|
122 | <command>traceroute</command>, so decide what's right for
|
---|
123 | your individual situation.</para>
|
---|
124 |
|
---|
125 | <para>The goal of BLFS is to be completely FHS compliant, so if you do leave the
|
---|
126 | <command>traceroute</command> binary SUID <systemitem
|
---|
127 | class="username">root</systemitem>, then you should move
|
---|
128 | <filename>traceroute</filename> to <filename class='directory'>/usr/bin</filename>
|
---|
129 | with the following command:</para>
|
