Synopsis |
19 |
======== |
20 |
|
21 |
Multiple integer overflow vulnerabilities have been discovered in |
22 |
Python, possibly resulting in the execution of arbitrary code or a |
23 |
Denial of Service. |
24 |
|
25 |
Background |
26 |
========== |
27 |
|
28 |

Description |
41 |
=========== |
42 |
|
43 |
Slythers Bro discovered multiple integer overflows in the imageop |
44 |
module, one of them in the tovideo() method, in various locations in |
45 |
files imageop.c, rbgimgmodule.c, and also in other files. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
A remote attacker could entice a user to process specially crafted |
51 |
images with an application using the Python imageop module, resulting |
52 |
in the execution of arbitrary code with the privileges of the user |
53 |
running the application, or a Denial of Service. Note that this |
54 |
vulnerability may or may not be exploitable, depending on the |
55 |
application using the module. |
56 |
|
57 |
Workaround |
58 |
========== |
59 |
|
60 |
