Ubuntu 5.04 / 5.10 : mozilla-thunderbird vulnerabilities (USN-297-3)

high Nessus Plugin ID 27872

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-297-1 fixed several vulnerabilities in Thunderbird for the Ubuntu 6.06 LTS release. This update provides the corresponding fixes for Ubuntu 5.04 and Ubuntu 5.10.

For reference, these are the details of the original USN :

Jonas Sicking discovered that under some circumstances persisted XUL attributes are associated with the wrong URL. A malicious website could exploit this to execute arbitrary code with the privileges of the user. (MFSA 2006-35, CVE-2006-2775)

Paul Nickerson discovered that content-defined setters on an object prototype were getting called by privileged UI code.
It was demonstrated that this could be exploited to run arbitrary web script with full user privileges (MFSA 2006-37, CVE-2006-2776).

Mikolaj Habryn discovered a buffer overflow in the crypto.signText() function. By sending an email with malicious JavaScript to an user, and that user enabled JavaScript in Thunderbird (which is not the default and not recommended), this could potentially be exploited to execute arbitrary code with the user's privileges. (MFSA 2006-38, CVE-2006-2778)

The Mozilla developer team discovered several bugs that lead to crashes with memory corruption. These might be exploitable by malicious websites to execute arbitrary code with the privileges of the user. (MFSA 2006-32, CVE-2006-2779, CVE-2006-2780)

Masatoshi Kimura discovered a memory corruption (double-free) when processing a large VCard with invalid base64 characters in it. By sending a maliciously crafted set of VCards to a user, this could potentially be exploited to execute arbitrary code with the user's privileges. (MFSA 2006-40, CVE-2006-2781)

Masatoshi Kimura found a way to bypass web input sanitizers which filter out JavaScript. By inserting 'Unicode Byte-order-Mark (BOM)' characters into the HTML code (e. g.
'<scr[BOM]ipt>'), these filters might not recognize the tags anymore; however, Thunderbird would still execute them since BOM markers are filtered out before processing a mail containing JavaScript. (MFSA 2006-42, CVE-2006-2783)

Kazuho Oku discovered various ways to perform HTTP response smuggling when used with certain proxy servers. Due to different interpretation of nonstandard HTTP headers in Thunderbird and the proxy server, a malicious HTML email can exploit this to send back two responses to one request. The second response could be used to steal login cookies or other sensitive data from another opened web site. (MFSA 2006-33, CVE-2006-2786)

It was discovered that JavaScript run via EvalInSandbox() can escape the sandbox. Malicious scripts received in emails containing JavaScript could use these privileges to execute arbitrary code with the user's privileges. (MFSA 2006-31, CVE-2006-2787).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
