Subject: Security ERRATA Critical: thunderbird on SL5.x, SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Wednesday 20th February 2013 19:16:37 UTC (over 3 years ago)
Synopsis:          Critical: thunderbird security update
Issue Date:        2013-02-19
CVE Numbers:       CVE-2013-0783
                    CVE-2013-0775
                    CVE-2013-0776
                    CVE-2013-0780
                    CVE-2013-0782
--

Several flaws were found in the processing of malformed content. Malicious
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2013-0775,
CVE-2013-0780, CVE-2013-0782, CVE-2013-0783)

It was found that, after canceling a proxy server's authentication 
prompt, the
address bar continued to show the requested site's address. An attacker 
could
use this flaw to conduct phishing attacks by tricking a user into believing
they are viewing trusted content. (CVE-2013-0776)

Note: All issues cannot be exploited by a specially-crafted HTML mail 
message
as JavaScript is disabled by default for mail messages. They could be 
exploited
another way in Thunderbird, for example, when viewing the full remote 
content
of an RSS feed.

Important: This erratum upgrades Thunderbird to version 17.0.3 ESR. 
Thunderbird
17 is not completely backwards-compatible with all Mozilla add-ons and
Thunderbird plug-ins that worked with Thunderbird 10.0. Thunderbird 17 
checks
compatibility on first-launch, and, depending on the individual 
configuration
and the installed add-ons and plug-ins, may disable said Add-ons and 
plug-ins,
or attempt to check for updates and upgrade them. Add-ons and plug-ins 
may have
to be manually updated.

After installing the update, Thunderbird must be restarted for the changes
to take effect.
