Synopsis |
16 |
======== |
17 |
|
18 |
A vulnerability in c-icap could result in Denial of Service. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
c-icap is an implementation of an ICAP server. It can be used with HTTP |
24 |
proxies that support the ICAP protocol to implement content adaptation |
25 |
and filtering services. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 net-proxy/c-icap < 0.2.6 >= 0.2.6 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
c-icap contains a flaw in the parse_request() function of request.c |
39 |
that may allow a remote denial of service. The issue is triggered when |
40 |
the buffer fails to contain a ' ' or '?' symbol, which will cause the |
41 |
end pointer to increase and surpass allocated memory. With a specially |
42 |
crafted request (e.g. via the OPTIONS method), a remote attacker can |
43 |
cause a loss of availability for the program. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker may cause 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 c-icap users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=net-proxy/c-icap-0.2.6" |
62 |
