Multiple flaws were found in the processing of malformed JavaScript content. An HTML mail containing such malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code as the user running Thunderbird. (CVE-2008-2801, CVE-2008-2802, CVE-2008-2803)

Several flaws were found in the processing of malformed HTML content.
An HTML mail containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code as the user running Thunderbird. (CVE-2008-2785, CVE-2008-2798, CVE-2008-2799, CVE-2008-2811)

Several flaws were found in the way malformed HTML content was displayed. An HTML mail containing specially crafted content could, potentially, trick a Thunderbird user into surrendering sensitive information. (CVE-2008-2800)

Two local file disclosure flaws were found in Thunderbird. An HTML mail containing malicious content could cause Thunderbird to reveal the contents of a local file to a remote attacker. (CVE-2008-2805, CVE-2008-2810)

A flaw was found in the way a malformed .properties file was processed by Thunderbird. A malicious extension could read uninitialized memory, possibly leaking sensitive data to the extension. (CVE-2008-2807)

A flaw was found in the way Thunderbird escaped a listing of local file names. If a user could be tricked into listing a local directory containing malicious file names, arbitrary JavaScript could be run with the permissions of the user running Thunderbird. (CVE-2008-2808)

A flaw was found in the way Thunderbird displayed information about self-signed certificates. It was possible for a self-signed certificate to contain multiple alternate name entries, which were not all displayed to the user, allowing them to mistakenly extend trust to an unknown site. (CVE-2008-2809)

Note: JavaScript support is disabled by default in Thunderbird. The above issues are not exploitable unless JavaScript is enabled.

Mozilla Firefox was updated to version 2.0.0.15, fixing various bugs including following security bugs :

CVE-2008-2798 CVE-2008-2799 MFSA-2008-21: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

CVE-2008-2800 MFSA-2008-22: Mozilla contributor moz_bug_r_a4 submitted a set of vulnerabilities which allow scripts from one document to be executed in the context of a different document. These vulnerabilities could be used by an attacker to violate the same-origin policy and perform an XSS attack.

CVE-2008-2801 MFSA-2008-23: Security researcher Collin Jackson reported a series of vulnerabilities which allow JavaScript to be injected into signed JARs and executed under the context of the JAR's signer. This could allow an attacker to run JavaScript in a victim's browser with the privileges of a different website, provided the attacker possesses a JAR signed by the other website.

CVE-2008-2802 MFSA-2008-24: Mozilla contributor moz_bug_r_a4 reported a vulnerability that allowed non-priviliged XUL documents to load chrome scripts from the fastload file. This could allow an attacker to run arbitrary JavaScript code with chrome privileges.

CVE-2008-2803 MFSA-2008-25: Mozilla contributor moz_bug_r_a4 reported a vulnerability which allows arbitrary JavaScript to be executed with chrome privileges. The privilege escalation was possible because JavaScript loaded via mozIJSSubScriptLoader.loadSubScript() was not using XPCNativeWrappers when accessing content. This could allow an attacker to overwrite trusted objects with arbitrary code which would be executed with chrome privileges when the trusted objects were called by the browser.

CVE-2008-2805 MFSA-2008-27: Opera developer Claudio Santambrogio reported a vulnerability which allows malicious content to force the browser into uploading local files to the remote server. This could be used by an attacker to steal arbitrary files from a victim's computer.

CVE-2008-2806 MFSA-2008-28: Security researcher Gregory Fleischer reported a vulnerability in the way Mozilla indicates the origin of a document to the Java plugin. This vulnerability could allow a malicious Java applet to bypass the same-origin policy and create arbitrary socket connections to other domains.

CVE-2008-2807 MFSA-2008-29: Mozilla developer Daniel Glazman demonstrated that an improperly encoded .properties file in an add-on can result in uninitialized memory being used. This could potentially result in small chunks of data from other programs being exposed in the browser.

CVE-2008-2808 MFSA-2008-30: Mozilla contributor Masahiro Yamada reported that file URLs in directory listings were not being HTML escaped properly when the filenames contained particular characters.
This resulted in files from directory listings being opened in unintended ways or files not being able to be opened by the browser altogether.

CVE-2008-2809 MFSA-2008-31: Mozilla developer John G. Myers reported a weakness in the trust model used by Mozilla regarding alternate names on self-signed certificates. A user could be prompted to accept a self-signed certificate from a website which includes alt-name entries. If the user accepted the certificate, they would also extend trust to any alternate domains listed in the certificate, despite not being prompted about the additional domains. This technique could be used by an attacker to impersonate another server.

CVE-2008-2810 MFSA-2008-32: Mozilla community member Geoff reported a vulnerability in the way Mozilla opens URL files sent directly to the browser. He demonstrated that such files were opened with local file privileges, giving the remote content access to read from the local filesystem. If a user opened a bookmark to a malicious page in this manner, the page could potentially read from other local files on the user's computer.

CVE-2008-2811 MFSA 2008-33: Security research firm Astabis, via the iSIGHT Partners GVP Program, reported a vulnerability in Mozilla's block reflow code. This vulnerablitity could be used by an attacker to crash the browser and run arbitrary code on the victim's computer.

The installed version of Firefox is affected by various security issues :

  - Several stability bugs leading to crashes which, in     some cases, show traces of memory corruption     (MFSA 2008-21).

  - A vulnerability involving violation of the same-origin     policy could allow for cross-site scripting attacks     (MFSA 2008-22).

  - JavaScript can be injected into the context of signed     JARs and executed under the context of the JAR's signer     (MFSA 2008-23).

  - By taking advantage of the privilege level stored in     the pre-compiled 'fastload' file, an attacker may be     able to run arbitrary JavaScript code with chrome     privileges (MFSA 2008-24).

  - Arbitrary code execution is possible in     'mozIJSSubScriptLoader.loadSubScript()' (MFSA 2008-25).

  - An attacker can steal files from known locations on a     victim's computer via originalTarget and DOM Range     (MFSA 2008-27).

  - It is possible for a malicious Java applet to bypass     the same-origin policy and create arbitrary socket     connections to other domains (MFSA 2008-28).

  - An improperly encoded '.properties' file in an add-on     can result in uninitialized memory being used, which     could lead to data formerly used by other programs     being exposed to the add-on code (MFSA 2008-29).

  - File URLs in directory listings are not properly HTML-     escaped when the filenames contained particular     characters (MFSA 2008-30).

  - A weakness in the trust model regarding alt names on     peer-trusted certs could lead to spoofing secure     connections to any other site (MFSA 2008-31).

  - URL shortcut files on Windows (for example, saved IE     favorites) could be interpreted as if they were in the     local file context when opened by Firefox, although     the referenced remote content would be downloaded and     displayed (MFSA 2008-32).

  - A crash in Mozilla's block reflow code could be used     by an attacker to crash the browser and run arbitrary     code on the victim's computer (MFSA 2008-33).

Updated SeaMonkey packages that fix a security issues are now available for Red Hat Enterprise Linux 2.1, Red Hat Enterprise Linux 3 and Red Hat Enterprise Linux 4.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

SeaMonkey is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.

Multiple flaws were found in the processing of malformed JavaScript content. A web page containing such malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code as the user running SeaMonkey. (CVE-2008-2801, CVE-2008-2802, CVE-2008-2803)

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code as the user running SeaMonkey.
(CVE-2008-2798, CVE-2008-2799, CVE-2008-2811)

Several flaws were found in the way malformed web content was displayed. A web page containing specially crafted content could potentially trick a SeaMonkey user into surrendering sensitive information. (CVE-2008-2800)

Two local file disclosure flaws were found in SeaMonkey. A web page containing malicious content could cause SeaMonkey to reveal the contents of a local file to a remote attacker. (CVE-2008-2805, CVE-2008-2810)

A flaw was found in the way a malformed .properties file was processed by SeaMonkey. A malicious extension could read uninitialized memory, possibly leaking sensitive data to the extension. (CVE-2008-2807)

A flaw was found in the way SeaMonkey escaped a listing of local file names. If a user could be tricked into listing a local directory containing malicious file names, arbitrary JavaScript could be run with the permissions of the user running SeaMonkey. (CVE-2008-2808)

A flaw was found in the way SeaMonkey displayed information about self-signed certificates. It was possible for a self-signed certificate to contain multiple alternate name entries, which were not all displayed to the user, allowing them to mistakenly extend trust to an unknown site. (CVE-2008-2809)

All SeaMonkey users should upgrade to these updated packages, which contain backported patches to resolve these issues.

New seamonkey packages are available for Slackware 11.0, 12.0, 12.1, and -current to fix security issues.

The remote host is affected by the vulnerability described in GLSA-200808-03 (Mozilla products: Multiple vulnerabilities)

    The following vulnerabilities were reported in all mentioned Mozilla     products:
    TippingPoint's Zero Day Initiative reported that an incorrect integer     data type is used as a CSS object reference counter, leading to a     counter overflow and a free() of in-use memory (CVE-2008-2785).
    Igor Bukanov, Jesse Ruderman and Gary Kwong reported crashes in the     JavaScript engine, possibly triggering memory corruption     (CVE-2008-2799).
    Devon Hubbard, Jesse Ruderman, and Martijn Wargers reported crashes in     the layout engine, possibly triggering memory corruption     (CVE-2008-2798).
    moz_bug_r_a4 reported that XUL documents that include a script from a     chrome: URI that points to a fastload file would be executed with the     privileges specified in the file (CVE-2008-2802).
    moz_bug_r_a4 reported that the mozIJSSubScriptLoader.LoadScript()     function only apply XPCNativeWrappers to scripts loaded from standard     'chrome:' URIs, which could be the case in third-party add-ons     (CVE-2008-2803).
    Astabis reported a crash in the block reflow implementation related to     large images (CVE-2008-2811).
    John G. Myers, Frank Benkstein and Nils Toedtmann reported a weakness     in the trust model used by Mozilla, that when a user accepts an SSL     server certificate on the basis of the CN domain name in the DN field,     the certificate is also regarded as accepted for all domain names in     subjectAltName:dNSName fields (CVE-2008-2809).
    The following vulnerabilities were reported in Firefox, SeaMonkey and     XULRunner:
    moz_bug_r_a4 reported that the Same Origin Policy is not properly     enforced on JavaScript (CVE-2008-2800).
    Collin Jackson and Adam Barth reported that JAR signing is not properly     implemented, allowing injection of JavaScript into documents within a     JAR archive (CVE-2008-2801).
    Opera Software reported an error allowing for arbitrary local file     upload (CVE-2008-2805).
    Daniel Glazman reported that an invalid .properties file for an add-on     might lead to the usage of uninitialized memory (CVE-2008-2807).
    Masahiro Yamada reported that HTML in 'file://' URLs in directory     listings is not properly escaped (CVE-2008-2808).
    Geoff reported that the context of Windows Internet shortcut files is     not correctly identified (CVE-2008-2810).
    The crash vulnerability (CVE-2008-1380) that was previously announced     in GLSA 200805-18 is now also also resolved in SeaMonkey binary     ebuilds.
    The following vulnerability was reported in Firefox only:
    Billy Rios reported that the Pipe character in a command-line URI is     identified as a request to open multiple tabs, allowing to open     'chrome' and 'file' URIs (CVE-2008-2933).
  Impact :

    A remote attacker could entice a user to view a specially crafted web     page or email that will trigger one of the vulnerabilities, possibly     leading to the execution of arbitrary code or a Denial of Service. It     is also possible for an attacker to trick a user to upload arbitrary     files or to accept an invalid certificate for a spoofed website, to     read uninitialized memory, to violate Same Origin Policy, or to conduct     Cross-Site Scripting attacks.
  Workaround :

    There is no known workaround at this time.

SeaMonkey was updated to version 1.1.11.

Problems fixed in the 1.1.11 update: CVE-2008-2785 MFSA 2008-34: An anonymous researcher, via TippingPoint's Zero Day Initiative program, reported a vulnerability in Mozilla's internal CSSValue array data structure. The vulnerability was caused by an insufficiently sized variable being used as a reference counter for CSS objects. By creating a very large number of references to a common CSS object, this counter could be overflowed which could cause a crash when the browser attempts to free the CSS object while still in use. An attacker could use this crash to run arbitrary code on the victim's computer.

Problems fixed in the 1.1.10 update: CVE-2008-2811 MFSA 2008-33:
Security research firm Astabis reported a vulnerability in Firefox 2 submitted through the iSIGHT Partners GVP Program by Greg McManus, Primary GVP Researcher. The reported crash in Mozilla's block reflow code could be used by an attacker to crash the browser and run arbitrary code on the victim's computer.

CVE-2008-2810 MFSA-2008-32: Mozilla community member Geoff reported a vulnerability in the way Mozilla opens URL files sent directly to the browser. He demonstrated that such files were opened with local file privileges, giving the remote content access to read from the local filesystem.

MFSA-2008-26: As a follow-up to vulnerability reported in MFSA 2008-12 Mozilla has checked similar constructs in the rest of the MIME handling code. Although no further buffer overflows were found we changed several function calls to use safer versions of the string routines that will be more robust in the face of future code changes.

CVE-2008-2803 MFSA-2008-25: Mozilla contributor moz_bug_r_a4 reported a vulnerability which allows arbitrary JavaScript to be executed with chrome privileges. The privilege escalation was possible because JavaScript loaded via mozIJSSubScriptLoader.loadSubScript() was not using XPCNativeWrappers when accessing content. This could allow an attacker to overwrite trusted objects with arbitrary code which would be executed with chrome privileges when the trusted objects were called by the browser.

These vulnerabilities could be used by an attacker to violate the same-origin policy and perform an XSS attack.

CVE-2008-2798 CVE-2008-2799 MFSA-2008-21: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
