Synopsis
========
PHP includes an XML-RPC implementation which allows remote attackers to
execute arbitrary PHP script commands.
Background
==========
PHP is a general-purpose scripting language widely used to develop
web-based applications. It can run inside a web server using the
mod_php module or the CGI version of PHP, or can run stand-alone in a
CLI.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-php/php < 4.4.0 >= 4.4.0
Description
===========
James Bercegay has discovered that the XML-RPC implementation in PHP
fails to sanitize input passed in an XML document, which is used in an
"eval()" statement.
Impact
======
A remote attacker could exploit the XML-RPC vulnerability to execute
arbitrary PHP script code by sending specially crafted XML data to
applications making use of this XML-RPC implementation.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PHP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/php-4.4.0"

Title: dhcpcd: Denial of Service vulnerability
Date: July 15, 2005
Bugs: #98394
ID: 200507-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability in dhcpcd may cause the dhcpcd daemon to crash.
Background
==========
dhcpcd is a standards compliant DHCP client daemon. It requests an IP
address and other information from the DHCP server, automatically
configures the network interface, and tries to renew the lease time.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/dhcpcd < 1.3.22_p4-r11 >= 1.3.22_p4-r11
Description
===========
infamous42md discovered that dhcpcd can be tricked to read past the end
of the supplied DHCP buffer. As a result, this might lead to a crash of
the daemon.
Impact
======
With a malicious DHCP server an attacker could cause a Denial of
Service by crashing the DHCP client.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All dhcpcd users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/dhcpcd-1.3.22_p4-r11"

Title: Mozilla Thunderbird: Multiple vulnerabilities
Date: July 18, 2005
Bugs: #98855
ID: 200507-17
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Several vulnerabilities in Mozilla Thunderbird allow attacks ranging
from execution of script code with elevated privileges to information
leak.
Background
==========
Mozilla Thunderbird is the next-generation mail client from the Mozilla
project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mozilla-thunderbird < 1.0.5 >= 1.0.5
2 mozilla-thunderbird-bin < 1.0.5 >= 1.0.5
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
The following vulnerabilities were found and fixed in Mozilla
Thunderbird:
* "moz_bug_r_a4" and "shutdown" discovered that Thunderbird was
improperly cloning base objects (MFSA 2005-56).
* "moz_bug_r_a4" also reported that Thunderbird was overly trusting
contents, allowing privilege escalation via property overrides (MFSA
2005-41, 2005-44), that it failed to validate XHTML DOM nodes
properly (MFSA 2005-55), and that XBL scripts ran even when
Javascript is disabled (MFSA 2005-46).
* "shutdown" discovered a possibly exploitable crash in
InstallVersion.compareTo (MFSA 2005-50).
* Andreas Sandblad from Secunia reported that a child frame can call
top.focus() even if the framing page comes from a different origin
and has overridden the focus() routine (MFSA 2005-52).
* Georgi Guninski reported missing Install object instance checks in
the native implementations of XPInstall-related JavaScript objects
(MFSA 2005-40).
* Finally, Vladimir V. Perepelitsa discovered a memory disclosure bug
in JavaScript's regular expression string replacement when using an
anonymous function as the replacement argument (CAN-2005-0989 and
MFSA 2005-33).
Impact
======
A remote attacker could craft malicious email messages that would
leverage these issues to inject and execute arbitrary script code with
elevated privileges or help in stealing information.
Workaround
==========
There are no known workarounds for all the issues at this time.
Resolution
==========
All Mozilla Thunderbird users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=mail-client/mozilla-thunderbird-1.0.5"
All Mozilla Thunderbird binary users should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=mail-client/mozilla-thunderbird-bin-1.0.5"
