15 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"
