Mozilla Firefox and Thunderbird before 1.5.0.4 associates XUL attributes with the wrong URL under certain unspecified circumstances, which might allow remote attackers to bypass restrictions by causing a persisted string to be associated with the wrong URL.

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). A similar attack was discovered by moz_bug_r_a4 that leveraged SelectionObject notifications that were called in privileged context. (MFSA 2006-43, CVE-2006-2777)

Mikolaj Habryn discovered a buffer overflow in the crypto.signText() function. By tricking a user to visit a site with an SSL certificate with specially crafted optional Certificate Authority name arguments, 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)

Chuck McAuley reported that the fix for CVE-2006-1729 (file stealing by changing input type) was not sufficient to prevent all variants of exploitation. (MFSA 2006-41, CVE-2006-2782)

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, Mozilla would still execute them since BOM markers are filtered out before processing the page. (MFSA 2006-42, CVE-2006-2783)

Paul Nickerson noticed that the fix for CVE-2005-0752 (JavaScript privilege escalation on the plugins page) was not sufficient to prevent all variants of exploitation. (MFSA 2006-36, CVE-2006-2784)

Paul Nickerson demonstrated that if an attacker could convince a user to right-click on a broken image and choose 'View Image' from the context menu then he could get JavaScript to run on a site of the attacker's choosing. This could be used to steal login cookies or other confidential information from the target site. (MFSA 2006-34, CVE-2006-2785)

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 Mozilla and the proxy server, a malicious website 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 website. (MFSA 2006-33, CVE-2006-2786).

This update of Mozilla Thunderbird fixes the security problems fixed in version 1.5.0.4: MFSA 2006-31/CVE-2006-2787: EvalInSandbox in Mozilla Firefox and Thunderbird before 1.5.0.4 allows remote attackers to gain privileges via JavaScript that calls the valueOf method on objects that were created outside of the sandbox. MFSA 2006-32/CVE-2006-2780: Integer overflow in Mozilla Firefox and Thunderbird before 1.5.0.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via 'jsstr tagify,' which leads to memory corruption. MFSA 2006-32/CVE-2006-2779:
Mozilla Firefox and Thunderbird before 1.5.0.4 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) nested <option> tags in a select tag, (2) a DOMNodeRemoved mutation event, (3) 'Content-implemented tree views,' (4) BoxObjects, (5) the XBL implementation, (6) an iframe that attempts to remove itself, which leads to memory corruption. MFSA 2006-33/CVE-2006-2786: HTTP response smuggling vulnerability in Mozilla Firefox and Thunderbird before 1.5.0.4, when used with certain proxy servers, allows remote attackers to cause Firefox to interpret certain responses as if they were responses from two different sites via (1) invalid HTTP response headers with spaces between the header name and the colon, which might not be ignored in some cases, or (2) HTTP 1.1 headers through an HTTP 1.0 proxy, which are ignored by the proxy but processed by the client. MFSA 2006-35/CVE-2006-2775: Mozilla Firefox and Thunderbird before 1.5.0.4 associates XUL attributes with the wrong URL under certain unspecified circumstances, which might allow remote attackers to bypass restrictions by causing a persisted string to be associated with the wrong URL. MFSA 2006-37/CVE-2006-2776: Certain privileged UI code in Mozilla Firefox and Thunderbird before 1.5.0.4 calls content-defined setters on an object prototype, which allows remote attackers to execute code at a higher privilege than intended. MFSA 2006-38/CVE-2006-2778: The crypto.signText function in Mozilla Firefox and Thunderbird before 1.5.0.4 allows remote attackers to execute arbitrary code via certain optional Certificate Authority name arguments, which causes an invalid array index and triggers a buffer overflow. MFSA 2006-40/CVE-2006-2781: Double-free vulnerability in Mozilla Thunderbird before 1.5.0.4 and SeaMonkey before 1.0.2 allows remote attackers to cause a denial of service (hang) and possibly execute arbitrary code via a VCard that contains invalid base64 characters.
MFSA 2006-42/CVE-2006-2783: Mozilla Firefox and Thunderbird before 1.5.0.4 strips the Unicode Byte-order-Mark (BOM) from a UTF-8 page before the page is passed to the parser, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a BOM sequence in the middle of a dangerous tag such as SCRIPT.

This updates fixes several security problems in the Mozilla Firefox 1.5 browser and brings it up to 1.5.0.4 bugfix level. The full list is at:

MFSA-2006-41/CVE-2006-2782:
Firefox does not fix all test cases associated with CVE-2006-1729, which allows remote attackers to read arbitrary files by inserting the target filename into a text box, then turning that box into a file upload control. MFSA 2006-42/CVE-2006-2783: Mozilla Firefox strips the Unicode Byte-order-Mark (BOM) from a UTF-8 page before the page is passed to the parser, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a BOM sequence in the middle of a dangerous tag such as SCRIPT. MFSA 2006-43/CVE-2006-2777:
Unspecified vulnerability in Mozilla Firefox allows remote attackers to execute arbitrary code by using the nsISelectionPrivate interface of the Selection object to add a SelectionListener and create notifications that are executed in a privileged context.

A number of security vulnerabilities have been discovered and corrected in the latest Mozilla Thunderbird program.

Corporate 3 had contained the Mozilla suite however, due to the support cycle for Mozilla, it was felt that upgrading Mozilla to Firefox and Thunderbird would allow for better future support for Corporate 3 users. To that end, the latest Thunderbird is being provided for Corporate 3 users which fix all known vulnerabilities up to version 1.5.0.5, as well as providing new and enhanced features.

Corporate users who were using Mozilla for mail may need to explicitly install the new mozilla-thunderbird packages.

For 2006 users, no explicit installs are necessary.
