The remote host is affected by the vulnerability described in GLSA-200503-10 (Mozilla Firefox: Various vulnerabilities)

    The following vulnerabilities were found and fixed in Mozilla     Firefox:
    Michael Krax reported that plugins can be used     to load privileged content and trick the user to interact with it     (CAN-2005-0232, CAN-2005-0527)     Michael Krax also reported     potential spoofing or cross-site-scripting issues through overlapping     windows, image drag-and-drop, and by dropping javascript: links on tabs     (CAN-2005-0230, CAN-2005-0231, CAN-2005-0591)     Daniel de Wildt     and Gael Delalleau discovered a memory overwrite in a string library     (CAN-2005-0255)     Wind Li discovered a possible heap overflow in     UTF8 to Unicode conversion (CAN-2005-0592)     Eric Johanson     reported that Internationalized Domain Name (IDN) features allow     homograph attacks (CAN-2005-0233)     Mook, Doug Turner, Kohei     Yoshino and M. Deaudelin reported various ways of spoofing the SSL     'secure site' indicator (CAN-2005-0593)     Matt Brubeck reported     a possible Autocomplete data leak (CAN-2005-0589)     Georgi     Guninski discovered that XSLT can include stylesheets from arbitrary     hosts (CAN-2005-0588)     Secunia discovered a way of injecting     content into a popup opened by another website (CAN-2004-1156)     Phil Ringnalda reported a possible way to spoof Install source with     user:pass@host (CAN-2005-0590)     Jakob Balle from Secunia     discovered a possible way of spoofing the Download dialog source     (CAN-2005-0585)     Christian Schmidt reported a potential     spoofing issue in HTTP auth prompt tab (CAN-2005-0584)     Andreas     Sanblad from Secunia discovered a possible way of spoofing the Download     dialog using the Content-Disposition header (CAN-2005-0586)     Finally, Tavis Ormandy of the Gentoo Linux Security Audit Team     discovered that Firefox insecurely creates temporary filenames in     /tmp/plugtmp (CAN-2005-0578)   Impact :

    By setting up malicious websites and convincing users to     follow untrusted links or obey very specific drag-and-drop or download     instructions, attackers may leverage the various spoofing issues to     fake other websites to get access to confidential information, push     users to download malicious files or make them interact with their     browser preferences.
    The temporary directory issue allows     local attackers to overwrite arbitrary files with the rights of another     local user.
    The overflow issues, while not thought to be     exploitable, may allow a malicious downloaded page to execute arbitrary     code with the rights of the user viewing the page.
  Workaround :

    There is no known workaround at this time.

A Mozilla Foundation Security Advisory reports :

Plugins (such as flash) can be used to load privileged content into a frame. Once loaded various spoofs can be applied to get the user to interact with the privileged content. Michael Krax's 'Fireflashing' example demonstrates that an attacker can open about:config in a frame, hide it with an opacity setting, and if the attacker can get the victim to click at a particular spot (design some kind of simple game) you could toggle boolean preferences, some of which would make further attacks easier.

The 'firescrolling' example demonstrates arbitrary code execution (in this case downloading a file) by convincing the user to scroll twice.

Workaround: Disable JavaScript.

The remote host is affected by the vulnerability described in GLSA-200503-30 (Mozilla Suite: Multiple vulnerabilities)

    The following vulnerabilities were found and fixed in the Mozilla     Suite:
    Mark Dowd from ISS X-Force reported an exploitable     heap overrun in the GIF processing of obsolete Netscape extension 2     (CAN-2005-0399)     Michael Krax reported that plugins can be used     to load privileged content and trick the user to interact with it     (CAN-2005-0232, CAN-2005-0527)     Michael Krax also reported     potential spoofing or cross-site-scripting issues through overlapping     windows, image or scrollbar drag-and-drop, and by dropping javascript:
    links on tabs (CAN-2005-0230, CAN-2005-0231, CAN-2005-0401,     CAN-2005-0591)     Daniel de Wildt and Gael Delalleau discovered a     memory overwrite in a string library (CAN-2005-0255)     Wind Li     discovered a possible heap overflow in UTF8 to Unicode conversion     (CAN-2005-0592)     Eric Johanson reported that Internationalized     Domain Name (IDN) features allow homograph attacks (CAN-2005-0233)     Mook, Doug Turner, Kohei Yoshino and M.

    The GIF heap overflow could be triggered by a malicious GIF     image that would end up executing arbitrary code with the rights of the     user running Mozilla. The other overflow issues, while not thought to     be exploitable, would have the same impact     By setting up     malicious websites and convincing users to follow untrusted links or     obey very specific drag-and-drop or download instructions, attackers     may leverage the various spoofing issues to fake other websites to get     access to confidential information, push users to download malicious     files or make them interact with their browser preferences     The     temporary directory issue allows local attackers to overwrite arbitrary     files with the rights of another local user   Workaround :

A bug was found in the way Mozilla installed search plugins. If a user chooses to install a search plugin from a malicious site, the new plugin could silently overwrite an existing plugin. This could allow the malicious plugin to execute arbitrary code and stealm sensitive information. (CVE-2005-1156 CVE-2005-1157)

Several bugs were found in the Mozilla JavaScript engine. A malicious web page could leverage these issues to execute JavaScript with elevated privileges or steal sensitive information. (CVE-2005-1154 CVE-2005-1155 CVE-2005-1159 CVE-2005-1160)

Users of Mozilla are advised to upgrade to this updated package which contains Mozilla version 1.7.7 to correct these issues.

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2005:176 advisory.

  - security flaw (CVE-2004-1156, CVE-2005-0231, CVE-2005-0232, CVE-2005-0233, CVE-2005-0255, CVE-2005-0527,     CVE-2005-0578, CVE-2005-0584, CVE-2005-0585, CVE-2005-0586, CVE-2005-0588, CVE-2005-0589, CVE-2005-0590,     CVE-2005-0591, CVE-2005-0592, CVE-2005-0593)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A number of security vulnerabilities were fixed in the Mozilla Firefox 1.0.4 and Mozilla Suite 1.7.8 releases. Patches have been backported where appropriate; Corporate 3.0 is receiving the new Mozilla Suite 1.7.8 release.

The following issues have been fixed in both Mozilla Firefox and Mozilla Suite :

  - A flaw in the JavaScript regular expression handling     could lead to a disclosure of browser memory,     potentially exposing private data from web pages viewed,     passwords, or similar data sent to other web pages. It     could also crash the browser itself (CVE-2005-0989, MFSA     2005-33)

  - With manual Plugin install, it was possible for the     Plugin to execute JavaScript code with the installing     user's privileges (CVE-2005-0752 and MFSA 2005-34)

  - The popup for showing blocked JavaScript used the wrong     privilege context which could be sued for privilege     escalation (CVE-2005-1153 and MFSA 2005-35)

  - Cross-site scripting through global scope pollution     could lead an attacker to being able to run code in     foreign websites context, leading to the potential     sniffing of information or performing actions in that     context (CVE-2005-1154 and MFSA 2005-36)

  - Code execution through JavaScript via favicons     ('firelinking') could be used for privilege escalation     (CVE-2005-1155 and MFSA 2005-37)

  - Search plugin cross-site scripting ('firesearching')     (CVE-2005-1156, CVE-2005-1157, and MFSA 2005-38)

  - Arbitrary code execution via the Firefox sidebar panel     II (CVE-2005-1158 and MFSA 2005-39)

  - Missing Install object instance checks (CVE-2005-1159     and MFSA 2005-40)

  - Privilege escalation via DOM property overrides     (CVE-2005-1160 and MFSA 2005-41)

  - Code execution via javacript: IconURL (MFSA 2005-42)

  - Security check bypass by wrapping a javascript: URL in     the view-source: pseudo protocol (MFSA 2005-43)

  - Privilege escalation via non-DOM property overrides     (MFSA 2005-44)

In addition to the vulnerabilities previously noted, the following issues have been fixed in the Mozilla Suite 1.7.2 packages :

  - Bypass restriction on opening privileged XUL     (CVE-2005-0401 and MSF 2005-32)

  - Arbitrary code execution via a GIF processing error when     parsing obsolete Netscape extension 2 leading to an     exploitable heap overrun (CVE-2005-0401 and MFSA     2005-32)

  - International Domain Name support could allow for     characters that look similar to other english letters to     be used in constructing nearly perfect phishing sites     (MFSA 2005-29)

  - Predictable plugin temporary directory name (MFSA     2005-28)

  - Plugins can be used to load privileged content into a     frame (CVE-2005-0527 and MFSA 2005-27)

  - Cross-site scripting attack via dropping javascript:
    links on a tab (MFSA 2005-26)

  - Image dragging-and-drop from a web page to the desktop     preserve their original name and extension; if this were     an executable extension then the file would be executed     rather than opened in a media application (MFSA 2005-25)

  - HTTP authentication prompt tab spoofing (MFSA 2005-24)

  - Download dialog source can be disguised by using a host     name long enough that most significant parts are     truncated, allowing a malicious site to spoof the origin     of the file (MFSA 2005-23)

  - Download dialog spoofing via supplied     Content-Disposition header could allow for a file to     look like a safe file (ie. a JPEG image) and when     downloaded saved with an executable extension (MFSA     2005-22)

  - XSLT can include stylesheets from arbitrary hosts (MFSA     2005-20)

  - Memory handling flaw in Mozilla string classes that     could overwrite memory at a fixed location if     reallocation fails during string growth (MFSA 2005-18)

  - Install source spoofing with user:pass@host (MFSA     2005-17)

  - Spoofing download and security dialogs with overlapping     windows (MFSA 2005-16)

  - It is possible for a UTF8 string with invalid sequences     to trigger a heap overflow of converted Unicode data     (MFSA 2005-15)

  - SSL 'secure site' indicator spoofing (MFSA 2005-14)

  - Mozilla mail clients responded to cookie requests     accompanying content loaded over HTTP, ignoring the     setting of the preference     'network.cookie.disableCookieForMailNews' which could be     used to track people (MFSA 2005-11)

  - Browser responds to proxy authentication requests from     non-proxy servers (SSL/HTTPS) (MFSA 2005-09)

  - Snythetic middle-click event can steal clipboard     contents (MFSA 2005-08)

  - In windows with multiple tabs, malicious content in a     background tab can attempt to steal information intended     for the topmost tab by popping up a prompt dialog that     appears to come from the trusted site, or by silently     redirecting input focus to a background tab hoping to     catch the user inputting something sensitive (MFSA     2005-05)

  - Secure site lock can be spoofed with 'view-source:'     (MFSA 2005-04)

  - An insecure page triggering a load of a binary file from     a secure server will cause the SSL lock icon to appear;
    the certificate information is that of the binary file's     host and the location bar URL shows the original     insecure page (MFSA 2005-03)

  - Temporary files are saved with world-readable     permissions (MFSA 2005-02)

  - A vulnerability in the NNTP handling code could cause a     heap overflow and execute arbitrary code on the client     machine (isec-0020)

  - A number of other minor bugs were fixed as well.

Mandriva recommends all users to upgrade to these packages immediately.

The remote host is using Firefox. The remote version of this software contains the following security flaws: 
1) There is a flaw in the way that the browser handle scripting within 'tabbed' cross-domains.  An attacker exploiting this flaw would need to be able to coerce a user into clicking on a malicious URL which would then open a separate 'TAB' within the browser.  The attacker could then retrieve data relevant to other tabbed connections or execute code locally.
2)There is a flaw in the default about: config script that would allow an attacker to modify configuration data. In order to execute such an attack, the attacker would need to be able to entice the user into visiting or clicking on a malicious URL.  A successful attacker would be able to modify the local configuration file, resulting in enhanced access rights or other potential exploits.
