Mozilla Firefox through 27 sends HTTP Cookie headers without first validating that they have the required character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP response.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)

  - Mozilla: Malicious Extension could obtain auth codes from OAuth login flows (CVE-2020-6823)

  - Mozilla Firefox through 27 sends HTTP Cookie headers without first validating that they have the required     character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout     CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP     response. (CVE-2013-6167)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

(CVE-2013-6167)

  - Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension     in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain     sensitive information by sniffing the network during a session in which there was an incorrect decision to     accept a compromised and revoked certificate. (CVE-2014-8642)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Versions of Firefox 20.0 and older are potentially affected by the following security issues :

 - Remote memory-corruption vulnerabilities in the browser engine that could lead to arbitrary code execution. Successful exploits may allow an attacker to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition. (CVE-2013-0788, CVE-2013-0789, CVE-2013-0790)
  - A local privilege-escalation vulnerability exists due to a buffer-overflow in Mozilla Maintenance Service. An attacker requires local file system access to exploit this issue. Exploiting this issue allows attackers to execute arbitrary code with elevated privileges. (CVE-2013-0799)
  - The applications are prone to a denial-of-service vulnerability due to an an out-of-bounds write condition in the Cairo graphics library. (CVE-2013-0800)
  - A remote memory-corruption vulnerability exists due to an out-of-bounds read condition in the 'CERT_DecodeCertPackage()' function of the Network Security Services (NSS) library when decoding a certificate. (CVE-2013-0791)
  - A local privilege-escalation vulnerability exists due to an error when using Mozilla Updater. Specifically, the issue occurs when the malicious 'DLL' file is placed in a specific location on the local system before the Mozilla Updater is run. (CVE-2013-0797)
  - A remote memory-corruption vulnerability when processing crafted PNG images. Specifically, this issue occurs because certain grayscale PNG images are displayed improperly when "gfx.color_management.enablev4" is enabled. Successful exploits may allow an attacker to gain access to sensitive information. (CVE-2013-0792)
  - A remote memory-corruption vulnerability exists in WebGL rendering. Specifically, the issue occurs because the applications attempts to free memory that has not previously been allocated. The vulnerability only affects Linux users who have Intel Mesa graphics drivers. (CVE-2013-0796)
  - An information disclosure vulnerability exists. Specifically, this issue exists in tab-modal dialog boxes. An attacker can exploit this issue to overlay a page and show another site's content. (CVE-2013-0794)
  - A security-bypass vulnerability due to an error when cloning a node through the 'cloneNode()' method. An attacker can exploit this issue to bypass System Only Wrappers (SOW) and the same origin policy. (CVE-2013-0795)
  - A cross-site scripting vulnerability exists because of an error related to a 'baseURI' of a page in the history. An attacker can exploit this issue to spoof the URL displayed in the address bar while displaying a different page and execute script code. (CVE-2013-0793)
 - A flaw exists and is triggered during the handling of the 'browser.cookie' header. This may allow a context-dependent attacker to terminate a user's session on a website, which will not allow the attacker to log back in to the website until after the browser has been restarted. (CVE-2013-6167)
