15 Synopsis
16 ========
17
18 Vulnerabilities in PAM-MySQL can lead to a Denial of Service, making it
19 impossible to log into a machine.
20
21 Background
22 ==========
23
24 PAM-MySQL is a PAM module used to authenticate users against a MySQL
25 backend.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 sys-auth/pam_mysql < 0.7_rc1 >= 0.7_rc1
34
35 Description
36 ===========
37
38 A flaw in handling the result of pam_get_item() as well as further
39 unspecified flaws were discovered in PAM-MySQL.
40
41 Impact
42 ======
43
44 By exploiting the mentioned flaws an attacker can cause a Denial of
45 Service and thus prevent users that authenticate against PAM-MySQL from
46 logging into a machine. There is also a possible additional attack
47 vector with more malicious impact that has not been confirmed yet.
48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 All PAM-MySQL users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=sys-auth/pam_mysql-0.7_rc1"
