Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200412-15
(Ethereal: Multiple vulnerabilities)

There are multiple vulnerabilities in versions of Ethereal earlier
than 0.10.8, including:
Bug in DICOM dissection
discovered by Bing could make Ethereal crash (CAN 2004-1139).
An invalid RTP timestamp could make Ethereal hang and create a
large temporary file (CAN 2004-1140).
The HTTP dissector could
access previously-freed memory (CAN 2004-1141).
Brian Caswell
discovered that an improperly formatted SMB could make Ethereal hang
(CAN 2004-1142).

Impact :

An attacker might be able to use these vulnerabilities to crash
Ethereal, perform DoS by CPU and disk space utilization or even execute
arbitrary code with the permissions of the user running Ethereal, which
could be the root user.

Workaround :

For a temporary workaround you can disable all affected protocol
dissectors by selecting Analyze->Enabled Protocols... and deselecting
them from the list. However, it is strongly recommended to upgrade to
the latest stable version.
