15 Synopsis
16 ========
17
18 Squirrelmail fails to properly sanitize user input, which could lead to
19 a compromise of webmail accounts.
20
21 Background
22 ==========
23
24 SquirrelMail is a webmail package written in PHP. It supports IMAP and
25 SMTP, and can optionally be installed with SQL support.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 mail-client/squirrelmail < 1.4.3a-r2 >= 1.4.3a-r2
34
35 Description
36 ===========
37
38 SquirrelMail fails to properly sanitize certain strings when decoding
39 specially-crafted headers.
40
41 Impact
42 ======
43
44 By enticing a user to read a specially-crafted e-mail, an attacker can
45 execute arbitrary scripts running in the context of the victim's
46 browser. This could lead to a compromise of the user's webmail account,
47 cookie theft, etc.
48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 All SquirrelMail users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.3a-r2"
61
62 Note: Users with the vhosts USE flag set should manually use
63 webapp-config to finalize the update.
