autofs-5.0.7 - fix parse buffer initialization |
|
|
|
From: Ian Kent <ikent@redhat.com> |
|
|
|
When parsing a master map entry, if the mount point path is longer than |
|
the following map string the lexical analyzer buffer may not have a null |
|
terminator where it is expected. If the map name string also contains a |
|
string that is the same as a map type at the end the map name the map |
|
name is not constructed correctly because of this lack of a string |
|
terminator in the buffer. |
