|
|
The following vulnerabilities have been discovered in Wireshark.
|
|
Firstly, if the IPsec ESP parser is used it is susceptible to
|
|
off-by-one errors, this parser is disabled by default; secondly, the
|
|
SCSI dissector is vulnerable to an unspecified crash; and finally, the
|
|
Q.2931 dissector of the SSCOP payload may use all the available memory
|
|
if a port range is configured. By default, no port ranges are
|
|
configured.
|
|
</p>

<impact type="normal">
|
|
<p>
|
|
An attacker might be able to exploit these vulnerabilities, resulting
|
|
in a crash or the execution of arbitrary code with the permissions of
|
|
the user running Wireshark, possibly the root user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable the SCSI and Q.2931 dissectors with the "Analyse" and "Enabled
|
|
protocols" menus. Make sure the ESP decryption is disabled, with the
|
|
"Edit -> Preferences -> Protocols -> ESP" menu.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Wireshark users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.3"</code>
|
|
</resolution>
