|
||
|
gif2png contains a command line parsing vulnerability that may result
|
||
|
in a stack overflow due to an unexpectedly long input filename.

<impact type="normal">
|
||
|
<p>
|
||
|
A remote attacker could entice a user to open a specially crafted
|
||
|
image, possibly resulting in the execution of arbitrary code with the
|
||
|
privileges of the user running the application, or a Denial of Service.
|
||
|
Note that applications relying on gif2png to process images can also
|
||
|
trigger the vulnerability.

||
|

<workaround>
|
