Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200512-06
(Ethereal: Buffer overflow in OSPF protocol dissector)

iDEFENSE reported a possible overflow due to the lack of bounds
checking in the dissect_ospf_v3_address_prefix() function, part of the
OSPF protocol dissector.

Impact :

An attacker might be able to craft a malicious network flow that
would crash Ethereal. It may be possible, though unlikely, to exploit
this flaw to execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.

Workaround :

There is no known workaround at this time.
