Tavis Ormandy of the Google Security Team discovered that the NEEDBITS
|
|
macro in the inflate_dynamic() function in the file inflate.c can be
|
|
invoked using invalid buffers, which can lead to a double free.

<p>
|
|
Remote attackers could entice a user or automated system to open a
|
|
specially crafted ZIP file that might lead to the execution of
|
|
arbitrary code or a Denial of Service.
