Re: iDefense Security Advisory 10.02.07: Sun Microsystems Solaris FIFO FS Information Disclosure Vulnerability

Dear Amateur Security Studier PAPAPAPAPAPAPA,

The context in which the term memory leak is used should clue you 
in here. When used in this content, 'leaked' clearly means the 
contents are exposed to userspace. It clearly does not mean memory 
is allocated and then not freed. By the way, your posts are always 
stupid.
