15 Synopsis
16 ========
17
18 ELinks does not properly validate "smb://" URLs, making it vulnerable
19 to the execution of arbitrary Samba commands.
20
21 Background
22 ==========
23
24 ELinks is a text mode web browser.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 www-client/elinks < 0.11.2 >= 0.11.2
33
34 Description
35 ===========
36
37 Teemu Salmela discovered an error in the validation code of "smb://"
38 URLs used by ELinks, the same issue as reported in GLSA 200612-16
39 concerning Links.
40
41 Impact
42 ======
43
44 A remote attacker could entice a user to browse to a specially crafted
45 "smb://" URL and execute arbitrary Samba commands, which would allow
46 the overwriting of arbitrary local files or the upload or download of
47 arbitrary files. This vulnerability can be exploited only if
48 "smbclient" is installed on the victim's computer, which is provided by
49 the "samba" Gentoo package.
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time.
55
56 Resolution
57 ==========
58
59 All ELinks users should upgrade to the latest version:
60
61 # emerge --sync
62 # emerge --ask --oneshot --verbose ">=www-client/elinks-0.11.2"
