15 | Synopsis |
16 | ======== |
17 | |
18 | Ethereal is vulnerable to numerous vulnerabilities potentially |
19 | resulting in the execution of arbitrary code or abnormal termination. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | Ethereal is a feature-rich network protocol analyzer. |
25 | |
26 | Affected packages |
27 | ================= |
28 | |
29 | ------------------------------------------------------------------- |
30 | Package / Vulnerable / Unaffected |
31 | ------------------------------------------------------------------- |
32 | 1 net-analyzer/ethereal < 0.10.12 >= 0.10.12 |
33 | |
34 | Description |
35 | =========== |
36 | |
37 | There are numerous vulnerabilities in versions of Ethereal prior to |
38 | 0.10.12, including: |
39 | |
40 | * The SMB dissector could overflow a buffer or exhaust memory |
41 | (CAN-2005-2365). |
42 | |
43 | * iDEFENSE discovered that several dissectors are vulnerable to |
44 | format string overflows (CAN-2005-2367). |
45 | |
46 | * Additionally multiple potential crashes in many dissectors have |
47 | been fixed, see References for further details. |
48 | |
49 | Impact |
50 | ====== |
51 | |
52 | An attacker might be able to use these vulnerabilities to crash |
53 | Ethereal or execute arbitrary code with the permissions of the user |
54 | running Ethereal, which could be the root user. |
55 | |
56 | Workaround |
57 | ========== |
58 | |
59 | There is no known workaround at this time. |
60 | |
61 | Resolution |
62 | ========== |
63 | |
64 | All Ethereal users should upgrade to the latest version: |
65 | |
66 | # emerge --sync |
67 | # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.12" |
