Mozilla Firefox 1.5.0.2 and possibly other versions before 1.5.0.4, Netscape 8.1, 8.0.4, and 7.2, and K-Meleon 0.9.13 allows user-assisted remote attackers to open local files via a web page with an IMG element containing a SRC attribute with a non-image file:// URL, then tricking the user into selecting View Image for the broken image, as demonstrated using a .wma file to launch Windows Media Player, or by referencing an "alternate web page."

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:
http://www.mozilla.org/projects/security/known-vulnerabilities.html#fi refox1.5.0.4 MFSA 2006-31/CVE-2006-2787: EvalInSandbox 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: An Integer overflow 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: Firefox 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, 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 2006-34/CVE-2006-2785: Cross-site scripting (XSS) vulnerability in Mozilla Firefox allows user-complicit remote attackers to inject arbitrary web script or HTML by tricking a user into (1) performing a 'View Image' on a broken image in which the SRC attribute contains a JavaScript URL, or (2) selecting 'Show only this frame' on a frame whose SRC attribute contains a JavaScript URL. MFSA 2006-35/CVE-2006-2775: Mozilla Firefox 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 2006-36/CVE-2006-2784: The PLUGINSPAGE functionality in Mozilla Firefox allows remote user-complicit attackers to execute privileged code by tricking a user into installing missing plugins and selecting the 'Manual Install' button, then using nested javascript: URLs. MFSA 2006-37/CVE-2006-2776: Certain privileged UI code in Mozilla Firefox 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 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 2006-39/CVE-2006-1942: Mozilla Firefox allows user-complicit remote attackers to open local files via a web page with an IMG element containing a SRC attribute with a non-image file:// URL, then tricking the user into selecting View Image for the broken image, as demonstrated using a ,wma file to launch Windows Media Player, or by referencing an 'alternate web page.' 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.

Versions of Mozilla Firefox 1.5.x prior to 1.5.0.5 are affected by various security issues, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The remote Windows host contains a mail client that is affected by multiple vulnerabilities.  The remote version of Mozilla Thunderbird suffers from various security issues, at least one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The installed version of SeaMonkey contains various security issues, some of which could lead to execution of arbitrary code on the affected host subject to the user's privileges.

The installed version of Firefox is affected by various security issues, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The remote host is running a vulnerable version of Mozilla Thunderbird mail client. This version of Thunderbird is vulnerable to multiple flaws that might allow an attacker to launch Denial of Service attacks, buffer overflows, information disclosure, privilege escalation, and other issues.  An attacker exploiting these flaws would need to be able to convince a user to open or read a malicious email.  Successful exploitation would, at the most, give the attacker the ability to execute arbitrary code with the permissions of the user running Thunderbird. 

The remote host is using SeaMonkey. The installed version of SeaMonkey contains various security issues that may allow an attacker to execute code or escalate privileges on the remote browser.  An attacker exploiting these flaws would need to be able to convince a user to browse to a malicious URI.

Versions of Mozilla Firefox 1.5.x prior to 1.5.0.4 are affected by  multiple security flaws that could allow an attacker to execute arbitrary code, disable the service, or gain access to confidential data. An attacker exploiting this flaw would need to be able to convince a user to browse to a malicious URI.
