Synopsis |
16 |
======== |
17 |
|
18 |
A buffer overflow in Echoping might allow remote attackers to cause a |
19 |
Denial of Service condition. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Echoping is a small program to test performances of a |
25 |
remote host by sending it TCP packets. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 net-analyzer/echoping < 6.0.2_p434 >= 6.0.2_p434 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
A boundary error exists within the "TLS_readline()" function, which can |
39 |
be exploited to overflow a global buffer by sending an overly long |
40 |
encrypted HTTP reply to Echoping. Also, a similar boundary error exists |
41 |
within the "SSL_readline()" function, which can be exploited in the |
42 |
same manner. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
A remote attacker could send a specially crafted HTTP reply, possibly |
48 |
resulting in a Denial of Service condition. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All Echoping users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot -v ">=net-analyzer/echoping-6.0.2_p434" |
62 |
