Mozilla Firefox < 37.0 Multiple Vulnerabilities

High Nessus Network Monitor Plugin ID 8742


The remote host has a web browser installed that is vulnerable to multiple attack vectors.


Versions of Mozilla Firefox earlier than 37.0 are unpatched for the following vulnerabilities :

- A privilege escalation vulnerability exists which relates to anchor navigation. A remote attacker can exploit this to bypass same-origin policy protections, allowing a possible execution of arbitrary scripts in a privileged context. Note that this is a variant of CVE-2015-0818 that was fixed in Firefox 36.0.4. (CVE-2015-0801)
- Access to certain privileged internal methods is retained when navigating from windows created to contain privileged UI content to unprivileged pages. An attacker can exploit this to execute arbitrary JavaScript with elevated privileges. (CVE-2015-0802)
- Multiple type confusion issues exist that can lead to use-after-free errors, which a remote attacker can exploit to execute arbitrary code or cause a denial of service. (CVE-2015-0803, CVE-2015-0804)
- Multiple memory corruption issues exist related to off-main-thread compositing when rendering 2D graphics, which a remote attacker can exploit to execute arbitrary code or cause a denial of service. (CVE-2015-0805, CVE-2015-0806)
- A cross-site request forgery (XSRF) vulnerability exists in the sendBeacon() function due to cross-origin resource sharing (CORS) requests following 30x redirections. (CVE-2015-0807)
- An issue exists in WebRTC related to memory management for simple-style arrays, which may be used by a remote attacker to cause a denial of service. (CVE-2015-0808)
- An issue exists that allows a remote attacker to make the user's cursor invisible, possibly resulting in a successful clickjacking attack. Only OS X installations of Firefox are affected. (CVE-2015-0810)
- An out-of-bounds read issue exists in the QCMS color management library that could lead to an information disclosure. (CVE-2015-0811)
- An issue exists that can allow a man-in-the-middle attacker to bypass user-confirmation and install a Firefox lightweight theme by spoofing a Mozilla sub-domain. (CVE-2015-0812)
- A use-after-free vulnerability affects the AppendElements() function when the Fluendo MP3 plugin for GStreamer is used. A remote attacker could exploit this to execute arbitrary code or cause a denial of service (heap memory corruption) via a specially crafted MP3 file. (CVE-2015-0813)
- Multiple memory safety issues exist within the browser engine. A remote attacker can exploit these to corrupt memory and possibly execute arbitrary code. (CVE-2015-0814, CVE-2015-0815)
- A privilege escalation vulnerability exists related to documents loaded through a 'resource:' URL. An attacker can exploit this to load pages and execute JavaScript with elevated privileges. (CVE-2015-0816)


Upgrade to Firefox 37.0, or later.
