15 | Synopsis |
16 | ======== |
17 | |
18 | Several cache poisoning vulnerabilities have been found in BIND. |
19 | |
20 | Background |
21 | ========== |
22 | |
23 | ISC BIND is the Internet Systems Consortium implementation of the |
24 | Domain Name System (DNS) protocol. |
25 | |
26 | Affected packages |
27 | ================= |
28 | |
29 | ------------------------------------------------------------------- |
30 | Package / Vulnerable / Unaffected |
31 | ------------------------------------------------------------------- |
32 | 1 net-dns/bind < 9.4.3_p5 >= 9.4.3_p5 |
33 | |
34 | Description |
35 | =========== |
36 | |
37 | Multiple cache poisoning vulnerabilities were discovered in BIND. For |
38 | further information please consult the CVE entries and the ISC Security |
39 | Bulletin referenced below. |
40 | |
41 | Note: CVE-2010-0290 and CVE-2010-0382 exist because of an incomplete |
42 | fix and a regression for CVE-2009-4022. |
43 | |
44 | Impact |
45 | ====== |
46 | |
47 | An attacker could exploit this weakness to poison the cache of a |
48 | recursive resolver and thus spoof DNS traffic, which could e.g. lead to |
49 | the redirection of web or mail traffic to malicious sites. |
50 | |
51 | Workaround |
52 | ========== |
53 | |
54 | There is no known workaround at this time. |
55 | |
56 | Resolution |
57 | ========== |
58 | |
59 | All BIND users should upgrade to the latest version: |
60 | |
61 | # emerge --sync |
62 | # emerge --ask --oneshot --verbose ">=net-dns/bind-9.4.3_p5" |
