Roy Tam reported a use-after-free vulnerability in the
|
||
|
|
GIFReadNextExtension() function in lib/pngxtern/gif/gifread.c leading
|
||
|
|
to a memory corruption when reading a GIF image.

|

|
|
A remote attacker could entice a user to process a specially crafted
|
||
|
|
GIF image, possibly resulting in the execution of arbitrary code with
|
||
|
|
the privileges of the user running the application, or a Denial of
|
||
|
|
Service.

|

|
|
<workaround>
|

|
|
<p>
|
||
|
|
There is no known workaround at this time.
