Ethereal contains buffer overflow vulnerabilities in the GTP, ISAKMP, and
|
|
|
|
|
MEGACO protocol dissectors, and a heap overflow vulnerability in the SOCKS
|
|
|
|
|
protocol dissector, which could cause Ethereal to crash or to execute
|
|
|
|
|
arbitrary code.

<p>

|
|
|
A remote attacker could craft a malformed packet which would cause Ethereal
|
|
|
|
|
to crash or run arbitrary code with the permissions of the user running
|
|
|
|
|
Ethereal.

|
<workaround>
|
|
|
|
|
<p>
|
|
|
|
|
There is no known workaround at this time, other than to disable the GTP,
|
|
|
|
|
ISAKMP, MEGACO, and SOCKS protocol dissectors.

It is recommended that all Gentoo Linux users who are running
|

net-analyzer/ethereal 0.9.x upgrade:
