Description |
36 |
=========== |
37 |
|
38 |
Chris Evans reported multiple integer overflows in the expandtabs |
39 |
method, as implemented by (1) the string_expandtabs function in |
40 |
Objects/stringobject.c and (2) the unicode_expandtabs function in |
41 |
Objects/unicodeobject.c. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could exploit these vulnerabilities in Python |
47 |
applications or daemons that pass user-controlled input to vulnerable |
48 |
functions. The security impact is currently unknown but may include the |
49 |
execution of arbitrary code or a Denial of Service. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
