15 Synopsis
16 ========
17
18 The FreeRADIUS server is vulnerable to a buffer overflow and an SQL
19 injection attack, possibly allowing the compromise of the system.
20
21 Background
22 ==========
23
24 FreeRADIUS is an open source RADIUS authentication server
25 implementation.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 net-dialup/freeradius < 1.0.2-r3 >= 1.0.2-r3
34
35 Description
36 ===========
37
38 Primoz Bratanic discovered that the sql_escape_func function of
39 FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
40 discovered that FreeRADIUS fails to sanitize user-input before using it
41 in a SQL query, possibly allowing SQL command injection (BID 13540).
42
43 Impact
44 ======
45
46 By supplying carefully crafted input, a malicious user could cause a
47 buffer overflow or an SQL injection, possibly leading to the execution
48 of arbitrary code or disclosure and the modification of sensitive data.
49
50 Workaround
51 ==========
52
53 There are no known workarounds at this time.
54
55 Resolution
56 ==========
57
58 All FreeRADIUS users should upgrade to the latest available version:
59
60 # emerge --sync
61 # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r3"
