the CVE identifiers referenced below for details. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
A remote attacker could entice a user to open a specially crafted index |
46 |
file using Python's dumbdbm module, possibly resulting in execution of |
47 |
arbitrary code with the privileges of the process. |
48 |
|
49 |
A remote attacker could entice a user to process a specially crafted |
50 |
input stream using Python's zipimporter module, possibly allowing |
51 |
attackers to cause unspecified impact. |
52 |
|
53 |
A man in the middle attacker could strip out the STARTTLS command |
54 |
without generating an exception on the Python SMTP client application, |
55 |
preventing the establishment of the TLS layer. |
56 |
|
57 |
Workaround |
