GLSA-200805-05 : Wireshark: Denial of Service

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


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-200805-05
(Wireshark: Denial of Service)

Errors exist in:
the X.509sat dissector because of an uninitialized variable and the
Roofnet dissector because a NULL pointer may be passed to the
g_vsnprintf() function (CVE-2008-1561).
the LDAP dissector because a NULL pointer may be passed to the
ep_strdup_printf() function (CVE-2008-1562).
the SCCP dissector because it does not reset a pointer once the packet
has been processed (CVE-2008-1563).

Impact :

A remote attacker could exploit these vulnerabilities by sending a
malformed packet or enticing a user to read a malformed packet trace
file, causing a Denial of Service.

Workaround :

Disable the X.509sat, Roofnet, LDAP, and SCCP dissectors.
