Subject: [PATCH] sys-utils: (setpriv): fix potential memory leak
|
||
|
|
|
||
|
|
Dynamic memory, referenced by 'buf' is allocated by calling function 'xstrdup'
|
||
|
|
add then changed by calling of strsep function.
|
||
|
|
The free(buf) call is incorrect if buf != NULL, and points to some
|
||
|
|
place inside or outside the source string.
