xine-lib contains a bug where it is possible to overflow the vcd://
|
|
input source identifier management buffer through carefully crafted
|
|
playlists.

<impact type="normal">
|
|
<p>
|
|
An attacker may construct a carefully-crafted playlist file which will
|
|
cause xine-lib to execute arbitrary code with the permissions of the
|
|
user. In order to conform with the generic naming standards of most
|
|
Unix-like systems, playlists can have extensions other than .asx (the
|
|
standard xine playlist format), and made to look like another file
|
|
(MP3, AVI, or MPEG for example). If an attacker crafts a playlist with
|
|
a valid header, they can insert a VCD playlist line that can cause a
|
|
buffer overflow and possible shellcode execution.
|
|

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are encouraged to
|
|
upgrade to the latest available version of xine-lib.

<resolution>
|
|
<p>
|
|
All xine-lib users should upgrade to the latest version:
