Synopsis
========
Multiple Denial of Service vulnerabilities have been discovered in
Wireshark.
Background
==========
Wireshark is a network protocol analyzer with a graphical front-end.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/wireshark < 1.0.0 >= 1.0.0
Description
===========
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.
Resolution
==========
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.0"
