Severity:	high
Title:	Mozilla Thunderbird: Multiple vulnerabilities
Date:	01/04/2007
Bugs:	#158571
ID:	200701-03

Synopsis

Multiple vulnerabilities have been reported in Mozilla Thunderbird, some of which may allow the remote execution of arbitrary code.

Background

Mozilla Thunderbird is a popular open-source email client from the Mozilla Project.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-client/mozilla-thunderbird	< 1.5.0.9	>= 1.5.0.9	All supported architectures
mail-client/mozilla-thunderbird-bin	< 1.5.0.9	>= 1.5.0.9	All supported architectures

Description

Georgi Guninski and David Bienvenu discovered buffer overflows in the processing of long "Content-Type:" and long non-ASCII MIME headers. Additionally, Frederik Reiss discovered a heap-based buffer overflow in the conversion of a CSS cursor. Different vulnerabilities involving memory corruption in the browser engine were also fixed. Mozilla Thunderbird also contains less severe vulnerabilities involving JavaScript and Java.

Impact

An attacker could entice a user to view a specially crafted email that will trigger one of these vulnerabilities, possibly leading to the execution of arbitrary code. An attacker could also perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials. Note that the execution of JavaScript or Java applets is disabled by default and enabling it is strongly discouraged.

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-1.5.0.9"

All Mozilla Thunderbird binary release users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.5.0.9"
