Synopsis |
16 |
======== |
17 |
|
18 |
Wireshark is vulnerable to several security issues that may lead to a |
19 |
Denial of Service and/or the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Wireshark is a feature-rich network protocol analyzer. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|

------------------------------------------------------------------- |

Package / Vulnerable / Unaffected |

|
34 |
Description |
35 |
=========== |
36 |
|
37 |
The following vulnerabilities have been discovered in Wireshark. |
38 |
Firstly, if the IPsec ESP parser is used it is susceptible to |
39 |
off-by-one errors, this parser is disabled by default; secondly, the |
40 |
SCSI dissector is vulnerable to an unspecified crash; and finally, the |
41 |
Q.2931 dissector of the SSCOP payload may use all the available memory |
42 |
if a port range is configured. By default, no port ranges are |
43 |
configured. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
An attacker might be able to exploit these vulnerabilities, resulting |
49 |
in a crash or the execution of arbitrary code with the permissions of |
50 |
the user running Wireshark, possibly the root user. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
Disable the SCSI and Q.2931 dissectors with the "Analyse" and "Enabled |
56 |
protocols" menus. Make sure the ESP decryption is disabled, with the |
57 |
"Edit -> Preferences -> Protocols -> ESP" menu. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All Wireshark users should upgrade to the latest version: |
63 |
|
64 |
# emerge --sync |
65 |
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.3" |
66 |
