Firefox < 43 Multiple Vulnerabilities (Mac OS X)

critical Nessus Plugin ID 87474
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox installed on the remote Mac OS X host is prior to 43. It is, therefore, affected by the following vulnerabilities :

- Multiple unspecified memory corruption issues exist due to improper validation of user-supplied input. A remote attacker can exploit these issues by convincing a user to visit a specially crafted web page, resulting in the execution of arbitrary code. (CVE-2015-7201)

- Multiple unspecified memory corruption issues exist due to improper validation of user-supplied input. A remote attacker can exploit these issues by convincing a user to visit a specially crafted web page, resulting in the execution of arbitrary code. (CVE-2015-7202)

- An overflow condition exists in the LoadFontFamilyData() function due to improper validation of user-supplied input. A remote attacker can exploit this to cause a buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-7203)

- A flaw exists in the PropertyWriteNeedsTypeBarrier() function due to improper handling of unboxed objects during JavaScript variable assignments. A remote attacker can exploit this to execute arbitrary code.
(CVE-2015-7204)

- A flaw exists in the RtpHeaderParser::Parse() function due to improper handling of RTP headers. An unauthenticated, remote attacker can exploit this, via specially crafted RTP headers, to execute arbitrary code. (CVE-2015-7205)

- A same-origin bypass vulnerability exists that is triggered after a redirect when the function is used alongside an iframe to host a page. An attacker can exploit this to gain access to cross-origin URL information. (CVE-2015-7207)

- The SetCookieInternal() function improperly allows control characters (e.g. ASCII code 11) to be inserted into cookies. An attacker can exploit this to inject cookies. (CVE-2015-7208)

- A use-after-free error exists due to improper prevention of datachannel operations on closed PeerConnections. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code.
(CVE-2015-7210)

- A flaw exists in the ParseURI() function due to improper handling of a hash (#) character in the data: URI. An attacker can exploit this to spoof the URL bar.
(CVE-2015-7211)

- An integer overflow condition exists in the readMetaData() function due to improper validation of user-supplied input when handling a specially crafted MP4 file. An attacker can exploit this to execute arbitrary code. (CVE-2015-7213)

- A same-origin bypass vulnerability exists due to improper handling of 'data:' and 'view-source:' URIs. An attacker can exploit this to read data from cross-site URLs and local files. (CVE-2015-7214)

- An information disclosure vulnerability exists due to improper handling of error events in web workers. An attacker can exploit this to gain access to sensitive cross-origin information. (CVE-2015-7215)

- Multiple integer underflow conditions exist due to improper validation of user-supplied input when handling HTTP2 frames. An attacker can exploit these to crash the application, resulting in a denial of service.
(CVE-2015-7218, CVE-2015-7219)

- An overflow condition exists in the XDRBuffer::grow() function due to improper validation of user-supplied input. An attacker can exploit this to cause a buffer overflow, resulting in the execution of arbitrary code.
(CVE-2015-7220)

- An overflow condition exists in the GrowCapacity() function due to improper validation of user-supplied input. An attacker can exploit this to cause a buffer overflow, resulting in the execution of arbitrary code.
(CVE-2015-7221)

- An integer underflow condition exists in the bundled version of libstagefright in the parseChunk() function that is triggered when handling 'covr' chunks. An unauthenticated, remote attacker can exploit this, via specially crafted media content, to crash the application or execute arbitrary code. (CVE-2015-7222)

- A privilege escalation vulnerability exists in the Extension.jsm script due to a failure to restrict WebExtension APIs from being injected into documents without WebExtension principals. An attacker can exploit this to conduct a cross-site scripting attack, resulting in the execution of arbitrary script code in a user's browser session. (CVE-2015-7223)

Solution

Upgrade to Firefox 43 or later.
