Subject: [PATCH 2/2] lib-managesieve: Make sure str_unescape() won't be
|
||
|
|
writing past allocated memory
|
||
|
|
|
||
|
|
The previous commit should already prevent this, but this makes sure it
|
||
|
|
can't become broken in the future either. It makes the performance a tiny
|
||
|
|
bit worse, but that's not practically noticeable.
