Subject: [PATCH] fix string overflow in vtoc_volume_label_init
|
||
|
|
|
||
|
|
Originaly it tries to copy a 84B string into 4B field and reset also
|
||
|
|
the other fields thru the overflow. This doesn't work with recent GCC
|
||
|
|
and the security-related compile flags that are used in Fedora.
