Detail
======
Security advisory summaries:
1. Several vulnerabilities in the Mozilla Suite allow attacks ranging from
the execution of javascript code with elevated privileges to
information leakage.
2. Clam AntiVirus is vulnerable to integer overflows when handling several
file formats, potentially resulting in the execution of arbitrary code.

Synopsis
========
Several vulnerabilities in the Mozilla Suite allow attacks ranging from
the execution of javascript code with elevated privileges to
information leakage.
Background
==========
The Mozilla Suite is an all-in-one Internet application suite including
a web browser, an advanced e-mail and newsgroup client, IRC client and
HTML editor.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/mozilla < 1.7.10 >= 1.7.10
2 www-client/mozilla-bin < 1.7.10 >= 1.7.10
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
The following vulnerabilities were found and fixed in the Mozilla
Suite:
* "moz_bug_r_a4" and "shutdown" discovered that the Mozilla Suite was
improperly cloning base objects (MFSA 2005-56).
* "moz_bug_r_a4" reported that the suite failed to validate XHTML DOM
nodes properly (MFSA 2005-55).
* Secunia reported that alerts and prompts scripts are presented with
the generic title [JavaScript Application] which could lead to
tricking a user (MFSA 2005-54).
* Andreas Sandblad of Secunia reported that top.focus() can be called
in the context of a child frame even if the framing page comes from a
different origin and has overridden the focus() routine (MFSA
2005-52).
* Secunia reported that a frame-injection spoofing bug which was
fixed in earlier versions, was accidently bypassed in Mozilla Suite
1.7.7 (MFSA 2005-51).
* "shutdown" reported that InstallVersion.compareTo() might be
exploitable. When it gets an object rather than a string, the browser
would generally crash with an access violation (MFSA 2005-50).
* Matthew Mastracci reported that by forcing a page navigation
immediately after calling the install method can end up running in
the context of the new page selected by the attacker (MFSA 2005-48).
* "moz_bug_r_a4" reported that XBL scripts run even when Javascript
is disabled (MFSA 2005-46).
* Omar Khan, Jochen, "shutdown" and Matthew Mastracci reported that
the Mozilla Suite incorrectly distinguished between true events like
mouse clicks or keystrokes and synthetic events generated by a web
content (MFSA 2005-45).
Impact
======
A remote attacker could craft malicious web pages that would leverage
these issues to inject and execute arbitrary javascript code with
elevated privileges, steal cookies or other information from web pages,
or spoof content.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Mozilla Suite users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.10"
All Mozilla Suite binary users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-bin-1.7.10"

Title: Clam AntiVirus: Integer overflows
Date: July 26, 2005
Bugs: #100178
ID: 200507-25
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Clam AntiVirus is vulnerable to integer overflows when handling several
file formats, potentially resulting in the execution of arbitrary code.
Background
==========
Clam AntiVirus is a GPL anti-virus toolkit, designed for integration
with mail servers to perform attachment scanning. Clam AntiVirus also
provides a command line scanner and a tool for fetching updates of the
virus database.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.86.2 >= 0.86.2
Description
===========
Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is
vulnerable to integer overflows when handling the TNEF, CHM and FSG
file formats.
Impact
======
By sending a specially-crafted file an attacker could execute arbitrary
code with the permissions of the user running Clam AntiVirus.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Clam AntiVirus users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.86.2"
