15 Synopsis
16 ========
17
18 A large number of share connection requests could cause a Denial of
19 Service within Samba.
20
21 Background
22 ==========
23
24 Samba is a freely available SMB/CIFS implementation which allows
25 seamless interoperability of file and print services to other SMB/CIFS
26 clients.
27
28 Affected packages
29 =================
30
31 -------------------------------------------------------------------
32 Package / Vulnerable / Unaffected

36 Description
37 ===========
38
39 During an internal audit the Samba team discovered that a flaw in the
40 way Samba stores share connection requests could lead to a Denial of
41 Service.
42
43 Impact
44 ======
45
46 By sending a large amount of share connection requests to a vulnerable
47 Samba server, an attacker could cause a Denial of Service due to memory
48 consumption.
49
50 Workaround
51 ==========
52
53 There is no known workaround at this time.
54
55 Resolution
56 ==========
57
58 All Samba users should upgrade to the latest version:
59
60 # emerge --sync
61 # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.22-r3"
